The two graphs above show the total amounts of money that Ian and Jeremy each have deposited into their savings accounts for the first seven weeks after opening their accounts. After they made their initial deposits, how much more did Ian deposit each week than Jeremy?

Options

A. 200
B. 100
C. 50
D. 25

Answer

C

Explanation

The graph for Ian shows that the initial deposit was $100 and that each week the total amount deposited increased by $100. Therefore, Ian deposited $100 each week. The graph for Jeremy shows that the initial deposit was $300 and that each week the total amount deposited increased by $50. Therefore, Jeremy deposited $50 each week. Thus, Ian deposited $50 more than Jeremy did each week.
Choice A is incorrect. This is the difference between the initial deposits in the savings accounts. Choice B is incorrect. This is the amount Ian deposited each week. Choice D is incorrect. This is half the amount that Jeremy deposited each week.
