Question

Ali is putting money into a savings account. He starts with $450 in the savings account, and each week he adds $70.

Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Ali has
been adding money. Write an equation relating S to W. Then use this equation to find the total amount of money in the savings
account after 17 weeks.

Answer 1

The total amount of money in the savings account can be represented by the sum of the initial amount of money and the amount of money added each week multiplied by the number of weeks:

S = 450 + 70W

To find the total amount of money in the savings account after 17 weeks, we can substitute W = 17 into the equation:

S = 450 + 70(17)

S = 450 + 1190

S = 1640

Therefore, after 17 weeks of adding $70 to the savings account each week, the total amount of money in the account will be $1640.:)
