REVIEW: Candace purchased 6 gallons of gas for $13.56. What is the constant of proportionality that relates the cost in dollars, y, to the number of gallons, x?
Remember, the constant of proportionality is k = y/x
(1 point)
O $1.23 per gallon
© $2.26 per gallon
• $0.44 per gallon
O $3.04 per gallon
To find the constant of proportionality, we need to divide the cost by the number of gallons:
Constant of proportionality (k) = $13.56 / 6 gallons
k ≈ $2.26 per gallon
Therefore, the correct answer is © $2.26 per gallon.
