To prepare for a road trip, Jill filled up her 19-gallon tank. She estimates that her SUV will use about three gallons per hour. Write an equation to model the amount of gasoline, G, remaining in her tank after t hours.

• G = 19 – 3t

• G = 19 + 3t

• G = 3 - 19t

• G = 3 + 19t

Mike started a summer business of mowing lawns. However, before he could mow lawns, he needed to purchase supplies (a lawnmower among other needs). Mike spent $395 gathering necessary materials. He makes on average $60 per lawn, mowed. Write an equation to show Mike his earnings for L lawns mowed.

• m = 60L - 395

• m = 60L + 395

• m = 60 - 395L

• m = 60 + 395L
