Tofind:The constant of proportionality, equation relating cost to the numbers of gallons and the cost of 18.5 gallons.
Answer to Problem 3GP
The constant of proportionality is
Explanation of Solution
Given information:The cost of 13 gallons of gasoline is
Calculation:
Let the cost be C and the number of gallons be x then the constant of proportionality can be found by dividing C by x.
Substitute 41.47 for Cand 3 for x in the above formula.
The required equation is:
The cost of 18.5 gallons can be calculated as:
Therefore, the constant of proportionality is
