Question

(a) what was the greatest donation amount in a month?
(b) when did the greatest increase in donations occur?
options for (b): december to january, january to february, february to march, march to april
chart shows months (december, january, february, march, april) and donation amounts (1500, 1700, 1900, 2100, 2300) with corresponding bars.

Explanation:

Part (a)

Step1: Analyze the graph

The graph shows donation amounts for different months (December, January, February, March, April) with values on the y - axis (1500, 1700, 1900, 2100, 2300). We need to find the month with the highest bar (greatest donation).

Step2: Identify the highest bar

Looking at the graph, the bar for December seems to reach the highest value on the y - axis. Assuming the y - axis is in dollars, the greatest donation amount in a month is the value corresponding to the tallest bar. From the graph, December's donation is the highest, and if we assume the scale, the greatest donation amount is $2300$ (or the highest value on the y - axis that the December bar reaches).

Step1: Calculate the increase between consecutive months

• December to January: Let \(D\) be December's donation and \(J\) be January's. Calculate \(J - D\).
• January to February: Let \(J\) be January's and \(F\) be February's. Calculate \(F - J\).
• February to March: Let \(F\) be February's and \(M\) be March's. Calculate \(M - F\).
• March to April: Let \(M\) be March's and \(A\) be April's. Calculate \(A - M\).

Step2: Compare the increases

By visually inspecting the graph (the difference in bar heights), the increase from January to February (the difference between the height of January's bar and February's bar) is the largest among the given options (December to January, January to February, February to March, March to April).

Answer:

The greatest donation amount in a month is $\$2300$ (assuming the December bar reaches the 2300 mark on the y - axis).
