part b

a 2.5
b 3
c 3.5
d 4

Explanation:

Step1: Calculate cost of gasoline

Cost of gasoline is price per gallon times gallons, so \(2.85 \times g = 2.85g\).

Step2: Calculate cost of oil

Cost of oil is price per can times cans, so \(3.15 \times c = 3.15c\).

Step3: Total cost

Add the two costs together: \(2.85g + 3.15c\).

Answer:

\(2.85g + 3.15c\)
