Answer:
6 hours
Step-by-step explanation:
A: y=125+7x
B: y=110+10x
for A to be a better deal than B, 125+7x<110+10x has to be true
- subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3x
- divide by 3: 5<x
- so x has to be greater than 5, im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you

Step-by-step explanation:
a) Jodi's car traveled 38 miles per gallon of gas. We know this because by dividng the amount of miles traveled by number of gallons Jodi has in her car we can find how many miles she travels per gallon of gas.
So our equation would be 456 / 12 = 38
b) The cost per gallon of gas was $3.74. We can find this answer by dividing how much she paid ($44.88) by how many gallons she bought (12).
So our equation would be 44.88 / 12 = 3.74
