Question

Mal is putting money into a savings account. She starts with $350 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 Mal 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 19 weeks.

Answer 1

Mal starts with 350 dollar

Each week she adds $30.

W is number of weeks Mal adds money.

S is total amount of money in her account.

=> S =30W + 350

After W = 19 weeks, Mal will have 30 x 19 + 350 = 920 dollar

Answer 2

S=350+(30*w)
so
350+(30*19)=920
