Is 1 ft 2 sec a unit rate? explain.

no

Step-by-step explanation:

a unit rate would be the simplified version of that which would only have one unit of time, so 1 ft per 2 sec is not a unit rate, but .5 ft per 1 sec is

$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)
