Answer 1

$43

Explanation:

Given

`Savings = \$88`

`Earnings = \$29`

`Amount\ Left = \$74`

Required

Calculate the amount spent

First, we need to calculate the total amount she had.

`Total = Savings + Earnings`

`Total = \$88 + \$29`

`Total = \$117`

Represent amount spent with x.

The relationship between total amount, spending and amount left is:

`Total - x = Amount\ Left`

`\$117 - x = \$74`

Collect Like Terms

`x = \$117 - \$74`

`x = \$43`
