The length of the rectangle is increasing at a rate of 8 cm/s and its width is increasing at a rate of 3cm/s. When the length is 20 cm and the width is 10cm, how fast is the area of the rectangle increasing?

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
