Jennifer is saving money to buy a bike. The bike costs $165. She has $105 saved, and each week she adds $12 to her savings.
How long will it take her to save enough money to buy the bike?

5 weeks

Step-by-step explanation:

12x + 105 = 165 ---> subtract 105 on each side> 12x = 60> divide by 12 on each side > x = 5

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
