Question

Kalon has $175 and needs to save at least $700 for a new computer. If he can save $35 per week, what is the minimum number of weeks Kalon will need to save to reach his goal?

Answer 1

700-175=525
525:35=15
He must save $35 during 15 weeks to have his new computer

Answer 2

Answer:

15 weeks.

Explanation:

Let w represent number of weeks.

We have been given that Kalon can save $35 per week, so amount saved in w weeks would be
`35w`.

Kalon has $175, so total amount saved by Kalon after w weeks would be
`35w+175`.

Since Kalon needs to save at least $700 for a new computer, so his total savings should be greater than or equal to 700.

We can represent this information in an inequality as:

`35w+175\geq 700`

`35w+175-175\geq 700-175`

`35w\geq 525`

`(35w)/(35)\geq (525)/(35)`

`w\geq 15`

Therefore, Kalon will have to save at-least for 15 weeks to reach his goal.
