$12s - $25
Step-by-step explanation:
Given that:
Amount charged per scarve = $12
Cost of booth used = $25
Profit made for selling 's' scarve after paying for booth
Profit = Revenue - Expenditure
Revenue = cost per scarve * number of scarves sold
Revenue = $12 * s
Revenue = 12s
Expenditure = cost of booth
Expenditure = $25
Hence,
Profit made = $12s - $25
The equation that is equivalent is -2+(-7).
