Question

The school band has saved up $3200 for a field trip, but they still need to save the remaining 60%. What is the total cost of the field trip?

Answer 1

The trip cost `$8,000`

Explanation:

Suppose the trip cost `$x`
We are told that
`color(white)("XXX")x-3200=60%" of "x`

That is
`color(white)("XXX")x-3200= 60/100 x`
or
`color(white)("XXX")(x-3200) * 10 =6x`

`color(white)("XXX")10x-32000=6x`

`color(white)("XXX")4x=32000`

`color(white)("XXX")x=8000`
