The number a x 10^-2 is about 8 times greater than b x 10^-3
find the correct value of a and b
a. a = 3.1 and b = 2.5
b. a = 2.5 and b = 3.1
c. a = 2 and b = 1.2
d. a = 1.2 and b = 2

$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)

mean, 40.6
