Answer:
F. c = 0.10m + 30
Explanation:
If you try the first value of m in each of the equations, you find all give wrong answers except the first one:
c = 0.10m + 30
__
Here is what you get for m=5:
F c = 0.10(5) +30 = 30.50
G c = 30(5) +0.10 = 150.10
H c = 0.50(5) +30 = 32.50
J c = 30(5) +0.50 = 150.50
