Answer:
a. y(cost) = 4.95g + 5.45c
b. $91.12
Step-by-step explanation:
a. Joe bought g gallons of gasoline for 4.95, this can be represented as 4.95g. He bought c cans of oil for 5.45, this can be represented as 5.45c. Add them together to find the total cost, and it will look like this: y(cost) = 4.95g + 5.45c.
b. g = 9.6 gallons
c = 8 cans of oil
Plug these into the equation we did in part A
y(cost) = 4.95(9.6) + 5.45(8)
Solve
y(cost) = 47.52 + 43.6
y(cost) = 91.12
Therefore, if Joe bought 9.6 gallons of gasoline and 8 cans of oil, all in all he spent $91.12.
Hope this helps!!
