Question

Debra is putting money into a savings account. She starts with $750 in the savings account, and each week she adds $30.

Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Debra 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 16 weeks.

Answer 1

The equation relating S to W is:

S = 750 + 30W

where S is the total amount of money in the savings account (in dollars) and W is the number of weeks Debra has been adding money.

To find the total amount of money in the savings account after 16 weeks, we substitute W = 16 into the equation:

S = 750 + 30(16) = 750 + 480 = 1230

Therefore, the total amount of money in the savings account after 16 weeks is $1230

Answer 2

Equation 750 + (30 x w) = S

Solving for 16 weeks
30x16= 480 + 750 = 1,230
