Answer:
-15 + -3 = -18
Rob owes his father $18.
Step-by-step explanation:
Rob has to pay back the same amount of money that he took. Since he took 15 dollars, he has to give back 15 dollars which makes the 15 negative. The same goes for the 3 in the equation.
To find out the total amount Rob has to pay back, we have to add -15 and -3, which is -18.
A) cost = (cost/gallon)*gallons
.. 83.58 = 3.799*gallons

The SUV has a 22-gallon tank.
B) miles per gallon = miles/gallons

The gas mileage for the trip was 16 miles per gallon.
