Answer: the profit is $4750
Step-by-step explanation:
A hardware store pays $3500 for 42 lawnmowers. This means that the amount that the hardware store paid for one lawnmower would be
3500/42 = $500/6
Then the store sells the lawnmowers for $99 each. This means that the total revenue that the store got from selling 42 lawnmowers would be
500/6 × 99 = $8250
Profit = Revenue - cost
Therefore, profit that the store makes from the lawnmower sales is
8250 - 3500 = $4750
