Question

the graph below shows how much money was given to a charity over five months.

(a) what was the least donation amount in a month?

(b) when did the greatest increase in donations occur?

may to june
june to july
july to august
august to september

Explanation:

Step1: Find the least donation amount

By observing the graph, the lowest point on the y - axis (donation amount) is at September. The value at September is \(1500\) dollars.

Step2: Calculate the increase in donations for each period

• May to June: \(2100 - 1700=400\)
• June to July: \(1800 - 2100=- 300\) (decrease)
• July to August: \(1900 - 1800 = 100\)
• August to September: \(1500 - 1900=-400\) (decrease)

The greatest increase is from May to June.

Answer:

(a) \(1500\)
(b) May to June
