the last one 3.7, 3 3/4, 31/8, 3.89

Step-by-step explanation:

3.7=3.7

3 3/4= 3.75

31/8=3.875

3.89=3.89

$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)
