The ratio of children to adults on a school trip is initially 10: 1. This
doesn't meet government
regulations, so 5 more children and
5 more adults join the trip so that
the ratio is now 9: 1. How many
children are there 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)
