Tom put 18 gallons of mid grade gas in his truck and filled up his empty 5 gallon gas can with regular gas for his lawnmower at home he spent $59.91 the following week he put 14 gallons of midgrade gas in his truck in topped off his 5 gallon can with 1 gallon of regular gas if he paid $39.75 in the prices remain the same find the price per gallon of midgrade in regular gas

To most closely estimate the difference, I would round 62,980 to the nearest thousand, so it will be 63,000. That is because when rounding, 63,000 is large enough so that adding will be easy, and 62,980 is relatively close to 63,000.

I would round 49,625 to the nearest thousand, since it would make the subtraction easier and 49,625 is only 375 units away from 50,000.

63,000 - 50,000 = about 13,000.

Hope this helps!
