Jeremy makes $4.70 every time he mows a lawn but it costs him $6.80 to refill his lawn mower with gas. If Jeremy mows 5 lawns using 3 tanks of gas, how much did he profit?

Answer:he made profit of $3.1

Step-by-step explanation:

The relationship between revenue, cost and profit is expressed as

Profit = Revenue - Cost

Jeremy makes $4.70 every time he mows a lawn but it costs him $6.80 to refill his lawn mower with gas.

If Jeremy mows 5 lawns using 3 tanks of gas, it means that his revenue would be

5 * 4.7 = $23.5

Also, his total cost would be

3 * 6.8 = $20.4

Therefore, his profit would be

Profit = 23.5 - 20.4 = $3.1
