If tina traveled 3,600 miles in 9 hours on her plane flight to her vacation destination, how fast was the plane traveling? a. 400 mph b. 395 mph c. 405 mph d. 390 mph

$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)

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
