19.
The graph below shows the total accumulated dollars (in millions) spent by the Surf City government during For example, about million had been spent by the beginning of February and approximately million by the end of April. Approximately how many millions of dollars were spent during the summer months of June, July, and August?
Answer: B
Small hint:
Because the graph shows an accumulated total, the amount spent over a span of months is the increase in that total across the span
Big hint:
Read the height of the curve at the beginning of June and at the end of August, then subtract the two values
Solution:
The graph gives the total accumulated spending, so the amount spent during June, July, and August equals the accumulated total at the end of August minus the accumulated total at the beginning of June.
The curve is at a bit more than million at the beginning of June and a bit more than million by the end of August. The difference is about million.
Thus, the correct answer is B .
