Question

On Day 16, Ebony deposited $100 into her account. On each day after Day 16, segment 5, Ebony made a deposit, and those deposits were equal to each other.
(a) Explain how you can determine, just by looking at the graph, whether the amounts she deposited after Day 16 were each less than $100, $100, or more than $100.

(b) Use the graph to estimate B(21) in hundreds. Explain how you determined this estimate. Then show how you can estimate the amount of money Ebony deposited into her account each day after Day 16.

Answer 1

Step-by-step explanation:

Judging from the high of 400, her day 21 appears to be approx 300

if she put in 100 then the next five days she added a total of 200 more to reach 300

200/5 = $40 / day
