Question

Linda is putting money into a savings account. She starts with $450 in the savings account, and each week she adds $70 .

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

The equation is
S (w)=450+70w

The total amount of money in the savings account after 19 weeks is
S (19)=450+70×19
S (19)=1,780

Answer 2

450+added

S=450+70W would be the equation

then afet 19 weeks
W=19
S=450+70(19)
S=450+1330
S=1780



equation is
S=70W+450
after 19 weeks, has 1780
