[Question]If the price of a bag of cherries is $5 when the price of a bag of olives is $7, how much would Jordyn pay for buying 50 bags of each fruit and a 10% discount?
[Answer]At a 10 percent discount, Jordyn will pay 10 / 100% * $5 = $.50 less for a bag of cherries. To buy one of the cherries at a 10% discount Jordyn will pay $5 - $0.50 = $4.50. The cost of buying 50 bags of cherries at the 10% discount is 50 * 4.50 = $225. Also, at a 10% discount, Jordyn will pay 10 / 100 * $7 = $0.70 less for a bag of olives. The price of a bag of olives at a 10% discount is $7 - $0.70 = $6.3. To buy 50 bags of olives Jordyn will pay $6.3 * 50 = $315. The total cost of buying 50 bags of each fruit at a 10% discount is $315 + $225 = $540. The answer is 540.

[Question]Nikola is saving up for a bag of ant food before he can start his ant farm. He wants 400 ants in his farm. Each ant needs 2 ounces of food. Every ounce of ant food costs $.1. Nikola is saving up by raking leaves. He charges $5 to start a job and then he charges by the leaf. Each leaf he rakes costs 1 penny. He finally saved up enough money after he raked 6,000 leaves. How many jobs did he complete?
[Answer]The ants will need 800 ounces of food because 400 x 2 = 800. The ant food will cost $80 because 800 x .1 = 80. He has earned $60 from the leaves he has raked because 6000 leaves * $0.01 / leaf = $60. He earned $20 from all his jobs because 80 - 60 = 20. He completed 4 jobs because 20 / 5 = 4. The answer is 4.

[Question]Mark realizes that a lot of the friends on his friends list are people he doesn't talk to anymore. He keeps 40% of his friends list and then contacts the rest. Of those only 50% respond. He removes everyone who did not respond. If he had 100 friends how many does he have left after the removal?
[Answer]He contacted 1 - .4 = .6 of his friends. So he contacted 100 * .6 = 60 people. So he removes 60 / 2 = 30 people. So he has 100 - 30 = 70 friends left. The answer is 70.
