An airplane is flying at an altitude of 3,500 feet. It drops 680 feet, and then rises 725 feet. At what altitude is the airplane at now?

$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)

parallelogram is the   answer

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !
