Question

Please help! Israel added $80 to his savings. This added amount represents 1/8 of his total savings. If s represents the total savings, what equation could be used to determine the value of s?

Answer 1

`s+80=(1)/(8)s`

Explanation:

Let s represents the total Israel's savings.

Israel added $80 to his savings. Hence, he then had $(s+80).

This added amount represents
`(1)/(8)` of his total savings.
`(1)/(8)` of his total savings is

`(1)/(8)s`

Therefore,

`s+80=(1)/(8)s`
