Answer 1

Given:

The carpenter spent 7/8 of his money on bags of sand for the sandbox.

Let the amount that carpenter having be 'x'

`\text{amount spent on bags of sand=}(7)/(8)x`
`\text{Amount spent on decoration= }(1)/(16)x`
`x-(7x)/(8)-(x)/(16)=19.90`
`(16x-14x-x)/(16)=19.90`
`x=19.90*16`
`x=318.40`

The money carpenter start with $318.40
