Question

Charlie is putting money into a savings account. He starts with $550 in the savings account, and each week he adds $60. Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Charlie has been adding money. Write an equation relation S to W. Then use this equation to find the total amount of money in the savings account after 12 weeks.

A. S=550+60W
B. S=550−60W
C. S=60W−550
D. S=60W+550

Answer 1

The correct equation relating the total amount of money in Charlie's savings account to the number of weeks he has been adding money is A. S=550+60W. After 12 weeks, Charlie will have a total of $1,270 in his savings account.

Step-by-step explanation:

The question involves creating an equation to determine how much money Charlie will have in his savings account after a certain number of weeks. The correct equation to represent the relationship between the total amount of money in the savings account (S) and the number of weeks Charlie has been adding money (W) is A. S=550+60W. This equation takes the initial amount of $550 and adds $60 for each week.

To find the total amount of money in the account after 12 weeks, substitute 12 for W in the equation: S = 550 + 60(12). Doing the calculation, 60 times 12 equals 720, and when you add that to 550, the total S comes to $1,270.
