Q: A year ago, the total cost of buying a lawnmower was 2/5 times less than the cost it goes for now. If the cost was $1800 a year ago, calculate how much it would cost Mr. Lucian to buy 4 such lawnmowers.
A: If the price of a lawnmower was $1800 a year ago, 2 / 5 less than the cost right now, then it now costs 2 / 5 * 1800 = $720 more to buy one lawnmower. The total cost of buying one lawnmower right now is $1800 + $720 = $2520. To purchase 4 such lawnmowers, Mr. Lucian will have to pay $2520 * 4 = $10080. The answer is 10080.

Q: Jackson’s mom packs him a peanut butter and jelly sandwich for his school lunch on Wednesdays and Fridays. There are 36 weeks of school and Jackson has only missed 1 Wednesday and 2 Fridays. How many peanut butter and jelly sandwiches did he eat for lunch this school year?
A: 36 weeks of school x 2 days of the week = 72 days of school. 1 Wednesday + 2 Fridays = 3 days of school missed. 72 days of school – 3 days of school missed = 69 peanut butter and jelly sandwiches eaten. The answer is 69.

Q: A tractor trailer has a load of 50000 pounds. 10% of the weight gets unloaded at the first store, and 20% of the remaining load is removed at the second store. How much weight, in pounds, is left on the truck after the two deliveries?
A:
First Store:50000(.10) = 5000. 50000 - 5000 = 45000 pounds. Second Store:45000(.20) = 9000. 45000 - 9000 = 36000 pounds. The answer is 36000.
