Explanation:

Step1: Analyze Canadian buying power

To determine when Canadian money had the strongest buying power, we look for the time when 1 Canadian dollar could buy the most US dollars (higher value on the y - axis for Canadian dollars per US dollar? Wait, no, the x - axis is Canadian Dollars per US Dollar? Wait, the graph is "Canadian Dollars per US Dollar" on the x - axis? Wait, the y - axis is the value, and the x - axis is "Canadian Dollars per US Dollar"? Wait, no, the label is "Canadian Dollars per US Dollar" on the x - axis? Wait, the graph shows the value of US Dollar vs. Canadian Dollar, with the x - axis labeled "Canadian Dollars per US Dollar" and the y - axis (month) from 10/12 to 3/13. Wait, actually, when Canadian money has stronger buying power, it means that 1 Canadian dollar can buy more US dollars, so the value of "Canadian Dollars per US Dollar" would be lower? Wait, no, let's think in terms of exchange rate. If we have \( \text{Exchange Rate} = \frac{\text{Canadian Dollars}}{\text{US Dollar}} \), a lower exchange rate means that 1 US dollar can buy fewer Canadian dollars, which implies that 1 Canadian dollar can buy more US dollars (stronger Canadian buying power). So we look for the lowest value of "Canadian Dollars per US Dollar" on the graph. Looking at the graph, the lowest point (most to the left on the x - axis, since x - axis is Canadian Dollars per US Dollar) is around March? Wait, no, the x - axis values: 0.96, 0.97, 0.98, 0.99, 1.00, 1.01, 1.02, 1.03, 1.04. Wait, maybe I got the axes reversed. Let's re - interpret: the y - axis (vertical) is the value, and the horizontal axis is the exchange rate. Wait, the month is on the vertical axis? No, the right - hand side is the month (10/12, 11/12, 12/12, 1/13, 2/13, 3/13). So the horizontal axis is the exchange rate (Canadian Dollars per US Dollar), and the vertical axis is the month. So each point on the line corresponds to a month and an exchange rate. To find when Canadian money has the strongest buying power, we want the exchange rate where 1 Canadian dollar buys the most US dollars. That happens when the exchange rate (Canadian Dollars per US Dollar) is the lowest, because if \( \text{Exchange Rate} = \frac{C}{U} \) (C = Canadian dollar, U = US dollar), then \( U=\frac{C}{\text{Exchange Rate}} \). So a lower exchange rate means more US dollars per Canadian dollar. Looking at the graph, the lowest exchange rate (smallest value on the horizontal axis) occurs around March? Wait, no, the horizontal axis values: 0.96 is the leftmost, then 0.97, etc. Wait, the line on the graph: when is the exchange rate the lowest? Let's look at the points. The leftmost point (lowest exchange rate) is around March? Wait, the months are from 10/12 (bottom) to 3/13 (top). Wait, no, the vertical axis (right) is the month, with 10/12 at the bottom and 3/13 at the top. So as we move up the vertical axis (later months), we look at the exchange rate (horizontal axis). Wait, the graph line: at 10/12 (bottom month), the exchange rate is around 1.02? At 11/12, it jumps to 1.00? Then at 12/12, it goes up to 1.03? Wait, no, the x - axis is Canadian Dollars per US Dollar, so a value of 0.96 means 1 US dollar = 0.96 Canadian dollars (which would mean 1 Canadian dollar = \( \frac{1}{0.96}\approx1.0417 \) US dollars), and a value of 1.04 means 1 US dollar = 1.04 Canadian dollars (1 Canadian dollar = \( \frac{1}{1.04}\approx0.9615 \) US dollars). So stronger Canadian buying power is when 1 Canadian dollar buys more US dollars, i.e., when the exchange rate (US dollars per Canadian dollar) is higher, which is equivalent to the exchange rate (Canadian dollars per US dollar) being lower. So we need to find the month where the exchange rate (Canadian dollars per US dollar) is the lowest. Looking at the graph, the lowest exchange rate (smallest value on the x - axis) is around March (3/13), because the line is at the leftmost (lowest x - value) around March. Wait, no, maybe I have the axes wrong. Let's check the other part: US money's strongest buying power. US money's strongest buying power is when 1 US dollar buys the most Canadian dollars, i.e., exchange rate (Canadian dollars per US dollar) is the highest. So the highest exchange rate (largest x - value) is around October (10/12), because the line is at the rightmost (highest x - value) around October.

Step2: Analyze US buying power

For US money's strongest buying power, we want 1 US dollar to buy the most Canadian dollars. Using the exchange rate \( \text{Exchange Rate}=\frac{\text{Canadian Dollars}}{\text{US Dollar}} \), a higher exchange rate means more Canadian dollars per US dollar. Looking at the graph, the highest exchange rate (largest value on the x - axis) occurs around October (10/12), because the line is at the rightmost (highest x - value) at that month.

Answer:

Canadian money had the strongest buying power in March; US money had the strongest buying power in October.
