In still water, a boat averages 9 miles per hour. It takes the same amount of time to travel 28 miles downstream, with the current, as 8 miles upstream, against the current. What is the rate of the water’s current?

$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)

i think it is c hope that

n=1.75+1.75
