A study of 80 pupils was conducted on the modes of transportation when they travel back to their hometowns, 25 pupils travel by train and 48 pupils travel by train or car. If 7 pupils travel by train and car, 5 pupils travel by bus and train, and 2 pupils travel by all three modes of transportation, how many pupils do travel by bus or train but not by car? Only for genius.​

$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)
