## Selena2345 2 years ago The capacity of the gas tank in Jennifer"s car is x gallons. She can drive 28 miles for each gallon of gas in the tank. Jennifer filled the tank completely and drove 98 miles. She then stopped and added 2 more gallons of gas. Part A: How many gallons of gas did Jennifer use to drive 98 miles ? Part B: Write an equation to find how far Jennifer could drive with the gas in her gas tank. Part C: Use the equation from Part B to find how far Jennifer could drive if her gas tank has a capacity of 18.5 gallons.

well for a, divide 98 by 28

3. Selena2345

98/28=3.5

4. AriPotta

so a is 3.5 gallons

5. Selena2345

what about part b and part c

6. AriPotta

y = 28(x - 1.5)

7. AriPotta

do you know how i got that?

8. Selena2345

no

so x is the tank's capacity. and we know she only used 3.5 gallons. so x - 3.5. but then she added 2 gallons. so x - 3.5 + 2 which simplified is x - 1.5. and she can get 28 miles per gallon, so we multiply that by 28

with part c you just substitute x with 18.5
