Question

Sal wants to save more than $50. He starts with $10 and saves $2.50 each week

I want to know this problem as an inequalities

Answer 1

`10 + 2.50 w > 50`

Explanation:

Given

`Start =10`

`Rate = 2.50`

Total = More than 50

Required

Represent as an inequality

Represent the weeks with w.

So, his savings in w weeks is:

`Savings = Start + Rate * w`

`Savings = 10 + 2.50 * w`

`Savings = 10 + 2.50 w`

His saving is expected to be more than 50.

More than, here means greater than (>)

So, we have;

`Savings > 50`

`10 + 2.50 w > 50`
