To find the constant of proportionality that relates the cost in dollars, y, to the number of gallons, x, we can use the given information:
1. Candace purchased 6 gallons of gas for $13.56.
2. The cost of 1 gallon of gas can be calculated by dividing the total cost by the number of gallons:
Cost per gallon = Total cost / Number of gallons
= $13.56 / 6
= $2.26
3. The constant of proportionality is the cost per gallon, which is $2.26 in this case.
Therefore, the correct constant of proportionality that relates the cost in dollars to the number of gallons is $2.26.
Step-by-step explanation:
The constant unit rate :
$13.56 / 6 gal = $ 2.26 per gallon
each gallon 'x' adds 2.26 to the cost 'y'
