Question

Anna would like to purchase a new bike that cost $205. She already has saved $34. If she saves a maximum of $12 a week, the following inequality can be used to find the minimum number of weeks, w, it will take Anna to save the money to purchase the bike Please show the steps

Answer 1

$34 + 12w ≥ 205

Subtract 34 from both sides:

12w ≥ 171

Divide both sides by 12:

w ≥ 14.25

Since Anna must save for a whole number of weeks, the minimum number of weeks it will take Anna to save the money to purchase the bike is 15 weeks.
