Answer this question:During his summer break, Luke catches 2 fish every day for 30 days. If each fish gives him 2 fillets, then how many fish fillets does he have?
He catches 2 fish every day for 30 days so he catches 2 * 30 = 60 fish. Each fish yields 2 fillets so he has 2 * 60 = 120 fish fillets.

Answer this question:Francine drives 140km to work each day. If she does not go to work 3 days every week, find the total distance she drives to work for 4 weeks in kilometers.
There are 7 days in a week, so if he doesn't go to work for 3 days, he goes 7 - 3 = 4 days every week. He travels 140km each day for a weekly total of 140 * 4 = 560km. In 4 weeks he will travel a total of 4 * 560 = 2240km.
The answer is 2240.

Answer this question:John weighs one-quarter times more than what Mary weighs. Mary weighs 20 lbs less than Jamison's weight. If Mary weighs 160 lbs, what's the combined weight of the three?
If Mary weighs 160 lbs, Jamison weighs 160 lbs + 20 lbs = 180 lbs. If John weighs one - quarter less than what Mary weighs, he weighs 1 / 4 * 160 lbs = 40 lbs more. The total weight of John is 160 lbs + 40 lbs = 200 lbs. The total weight for the three is 200 lbs + 180 lbs + 160 lbs = 540 lbs.
The answer is 540.
