Answer:
12 gallons
Step-by-step explanation:
we can set up a ratio of gas/miles equals gas/miles
7 3/4 can be rewritten as 7.75
let 'g' = # gallons used for 250 miles
7.75/160 = g/250 After cross-multiplying you get:
1937.5 = 160g
divide each side by 160 to get value of 'g':
g = 12.11 to nearest hundredth
