8)A gas station charges $2.19 per gallon of gas. Use function notation to describe the relationship between the total cost C(g) and the number of gallons purchased g. (1 point)
C(g) = –2.19g
g = 2.19C(g)
C(g) = g + 2.19
C(g) = 2.19g
My Answers:
4)B
6)C
8)A
Are these correct???

#4 and 6 are correct,
#8 should be
C(g) = 2.19g , which looks like choice D
e.g if you bought 8 gallons
C(8) = 2.19(8) = 23.28
