Question

2.
Suzy wants to buy a bike. She currently has $30 in her wallet and plans on
saving $10 per week
b. How long will it take Suzy to buy a bike that costs $150? Show your work.

Answer 1

30+10p =150
150-30 = 120
10p=120
(10p=120)division by 10
P = 12

(P can be any variable)

Answer 2

P= per week

$30 +$10W= $150
-$30. $-30. Subtract $30 from $150
———————————
10P=120
—-- ——. Divide by 10 on both sides
10. 10

P= 12
It would take Suzy 12 days to buy a bike that cost $150
