Question: Sara is checking out two different stores to buy a computer. The first store offers a device for $950 with a 6% discount. The second sells the same computer for €920 with a 5% discount. What is the difference in price between the two stores?
Answer: The amount of discount in the first store 950 x 6 / 100 = $57. So, the device costs 950 - 57 = $893 in the first store. The amount of discount in the second store is 920 x 5 / 100 = $46. So, the device costs 920 - 46 = $874 in the second store. The difference in price is 893 - 874 = $19. The answer is 19.

Question: A fast-food chain offers free delivery for a minimum purchase of $18. Danny ordered 2 quarter-pounder burgers for $3.20 each, 2 large fries that cost $1.90 each, and 2 milkshakes that cost $2.40 each. How much more worth of food should he order to avail of the free delivery?
Answer: Two quarter - pounder burgers cost $3.20 x 2 = $6.40. Two large fries cost $1.90 x 2 = $3.80. Two milkshakes cost $2.40 x 2 = $4.80. The total amount spent for the burgers, fries, and shakes is $6.40 + $3.80 + $4.80 = $15. Therefore, he should order $18 - $15 = $3 worth of additional food to take advantage of the free food delivery. The answer is 3.

[Question]Miriam is trying to exercise more and figures if she counts her exercises it will be encouraging to see her numbers go up. On Monday she does 5 push-ups. On Tuesday she does 7 push-ups. On Wednesday she does twice as many push-ups as the day before. On Thursday she does half the number of total pushups she already did that week. Finally, on Friday she does as many pushups as the total number she did over the previous four days. How many pushups does Miriam do on Friday?
[Answer]
On Monday Miriam does 5 push - ups + 7 push - ups on Tuesday = 12 push - ups on both days. On Wednesday she does twice as many push - ups as she did on Tuesday, 7 x 2 = 14 push - ups on Wednesday. Over the first 3 days, she did a total of 14 + 12 = 26 pushups. On Thursday Miriam did 1 / 2 the same number of total pushups she had already done that week, so she did 1 / 2 x 26 = 13 pushups on Thursday. On Friday she does as many push - ups as the total of what she had done over the previous four days, so she did 5 + 7 + 14 + 13 = 39 push - ups on Friday. The answer is 39.
