The amount of profit

EVALUATION

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

Now Jeremy mows 5 lawns using 3 tanks of gas

Here

Price of 3 tanks of gas

= $ ( 3 × 6.80 )

= $ 20.40

Again earning from 5 lawns

= $ ( 5 × 4.70 )

= $ 23.50

So the amount profit

= $ ( 23.50 - 20.40 )

= $ 3.10
