Question

Latoya is putting money into a savings account. She starts with $350 in the savings account, and each week she adds $40 .

Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Latoya 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 12 weeks.

What is the total amount of money after 12 weeks: ?

Answer 1

$830.

Explanation:

The equation would be S=350+40W. If she starts with $350 dollars, you need to add it to the final total, which is why we have the 350+. 40W is showing that for every week (W) you are adding 40 dollars. Because there are 12 weeks where she adds $40, substitute 12 for W. Then solve the equation.

S=350+40(12)

S=350+480

S=830

Because S is the total amount of money in her account, there should be $830 in her account at the end of 12 weeks. Hope it helps!
