Explanation:

Given the expression ​c​ = 2.95​g​

since c represents cost

g represents how many gallons of gas were purchase

the terms that relates the cost to the numbers of gallons purchased is

2.5 which is equally the constant of proportionality

Therefore the constant of proportionality is 2.5
