Which of the following is a geometric sequence?
a. 3, 7, 11, 15, 19
b. 4, 6, 10, 16, 26
c. 4, 16, 64, 256

where is the triangle?

$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)
