Question: Jerry mows 8 acres of lawn each week. He mows ¾ of it with a riding mower that can cut 2 acres an hour. He mows the rest with a push mower that can cut 1 acre an hour. How long does Jerry mow each week?
Answer with step-by-step thinking: Jerry mows 8 acres x ¾ = 6 acres with a riding mower. It will take him 6 acres / 2 each hour = 3 hours. Jerry mows 8 acres – 6 acres mowed with a riding mower = 2 acres with a push mower. It will take him 2 acres x 1 hour = 2 hours. It takes Jerry a total of 3 hours on the riding mower + 2 hours on the push mower = 5 hours.
So the answer is 5.


Question: Lyra bought a pair of shoes at a 20% discount. If she paid $480, how much was the original price of the pair of shoes?
Answer with step-by-step thinking: Lyra only paid $480 for the pair of shoes which is only 100% - 20% = 80% of the original price. So let x be the original price. Then 0.8x = $480. Thus x = $480 / 0.8 = $600.
So the answer is 600.


Question: Nellie had 380 legos, but she lost 57 of them and gave her sister 24 legos. How many legos does she have now?
