Shamiks family is moving. they have to drive 2,520 miles. his dad says he...
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).
and then subtract $61.25 by the second thing he bought (the new string for the trimmer)
so in total it's $53.50 (53 dollars and 50 cents)
