Q: Cassy packs 12 jars of jam in 10 boxes while she packs 10 jars of jam in 30 boxes. If she has 500 jars of jams, how many jars of jam will she have left when all the boxes are full?
A: Cassy can pack 12 x 10 = 120 jars of jam in the 10 boxes. She can also pack 10 x 30 = 300 jars of jam in the 30 boxes. A total of 300 + 120 = 420 jars of jam can be packed in the boxes. So, 500 - 420 = 80 jars of jam will be left unpacked. The answer is 80.

Q: Mr. Callen bought 10 paintings at $40 each and 8 wooden toys at $20 each from the crafts store to resell at a profit. However, when he sold the items, the selling price of a painting was 10% less and the selling price of a hat 15% less. Calculate the total loss Mr. Callen made from the sale of the items.
A: If he sold a painting at a 10% loss, then he made a 10 / 100 * $40 = $4 loss on each painting. since he bought 10 paintings, the total loss he made from selling the paintings is 10 * $4 = $40. He also made a loss of 15 / 100 * 20 = $3 loss from selling each wooden toy. Since he bought 8 wooden toys, the total loss he made was 3 * 8 = $24. In total, Mr. Callen made a loss of $40 + $24 = $64 from the sales of the items. The answer is 64.
Question: A dog is being treated for fleas. One flea treatment gets rid of half the fleas. After four treatments, the dog has 14 fleas left. How many more fleas did the dog have before the flea treatments than after?
Answer: After three treatments, the dog had 14 * 2 = 28 fleas. After two treatments, the dog had 28 * 2 = 56 fleas. After one treatment, the dog had 56 * 2 = 112 fleas. Before any treatments, the dog had 112 * 2 = 224 fleas. Thus, the dog had 224 - 14 = 210 more fleas before the treatments than after. The answer is 210.
Q: Amelia has $60 to spend on her dinner at a restaurant. The first course costs $15 and the second course $5 more. The cost of the dessert is 25% of the price of the second course. How much money will Amelia have left after buying all those meals?
