If you add all the numbers on the right together you get -35 then you divide by 5 which gives you the average of -7*F
Answer:No it is not proportional
Step-by-step explanation:
4 hours=$37
7 hours=$64.75
I t is not proportional because if 4 hours =$37 then 6 hours is supposed to be around $70 but 7 hours=$64.75
Basically because you can break any square root of non-perfect square into the square root of prime factors.
1 /5 = 0 . 2
45 * . 2 = 9
