Answer 1

Answer:

She will save $\ 24.44$ by driving.

Step-by-step explanation:

Given: Jocelyn lives in Granite Falls. She wants to visit Megan in Spokane Valley. She can fly from Seattle to Spokane for $\ 96.20$ round trip or she can drive a total of $650$ miles round trip. If her car gets $25$ miles per gallon, and gas costs $\ 2.76$/gallon.

To find: how much money will she save by driving?

Solution:

The total cost for flying Seattle to Spokane is $\ 96.20$.

Now, in order to find how much money will she save by driving, we need to first find the total cost for driving a total of $650$ miles round trip.

So, total distance $=650$ miles.

Car covers $25$ miles per gallon.

So, to cover $650$ miles, $\frac{650}{25} =26$ gallons of gas is required.

Now, gas costs $\ 2.76$/gallon.

Therefore, total charge $=26\times2.76=\ 71.76$.

So, total money saved$=\ 96.20-\ 71.76=\ 24.44$

Hence, she will save $\ 24.44$ by driving.
