Here is what'd you do:
Ignore the $78.80 at the moment and focus on the $6.60 an hour and she worked 8 hours.
So, basically you'd do 6.60 * 8 (or 660*8 if you aren't allowed a calculator)
For 660*8 you'd get:
5280. move the decimal over twice.
$52.80 , if you are allowed a calculator you would have just done 6.60 * 8
So now you know she got $52.80 just working hourly.
Subtract $78.80 from $52.80

Answer:
Yes, it is proportional.
Step-by-step explanation:
Anything with "A =" is always going to be proportional.
Let's make two expressions.
4.92+3.79x
This represents the car service's cost, which x being miles.
4.2x
This is the most Jason wants to spend. Let's make them equal.
4.92+3.79x=4.2x
We need to get x by itself, Let subtract 3.79x from both sides.
4.92=0.41x
Let's divide.
4.92÷0.41=12
So, he should not drive no more than 12 miles.
