Question

Write an inequality and solve.
15.) Sam has $25 and plans on saving $15 a week until he has at least $150. Write an inequality
to represent this scenario then find how long Sam needs to save.

Answer 1

Answer:

25 + 15n ≥ 150

Step-by-step explanation:

The term at least mean the amount saved is greater than or equal to 150

Let the number of weeks he intends to save be n

Amount saved after n weeks without the plan is:

15n

Add plan amount

= 25 + 15n

Add inequality

25 + 15n ≥ 150
