Question

patty needs a total of $85 to buy a bicycle. She has already saved $35. If she saves $10 a week from her earnings, what is the least number of weeks she must work to have enough money to buy the bicycle?

Answer 1

Patty needs 85$. She has 35. So she needs 85-35 = 50$ more.
She earns 10$per week, and she needs 50$.
10w = 50. Where w is the number of weeks needed.
Solve that equation to get the number of weeks

Answer 2
