Answer:
y = 102*x
Step-by-step explanation:
y=a*x
x: distance
y: calories
816=a*8
a= 816/8= 102
The car goes 23.2 miles every gallon, so with 15 gallons (15 * 23.2 = 348) it can go 348 miles. With the extra .25 that the car has, it can go 0.25 * 23.2 = 5.8 miles. 348 miles plus the 5.8 miles gets you 353.8 miles on 15.25 gallons.
