Answer 1

Explanation:

60Divided by 0.8 equals75

Answer 2

`0.8n \leqslant 60`

Simplified:

`n \leqslant 75`

Explanation:

`125 - 65 = 60`

They have $60 left.

Let n be the number of balloons.

Amount of money spent on n number of balloons:

`0.8n`

Since they do not want to exceed the remaining $60, the inequality will be:

`0.8n \leqslant 60`

Solving it:

`0.2n \leqslant 15`

`n \leqslant 75`
