Q: The ratio of the amount of money Cara, Janet, and Jerry have is 4:5:6. If the total amount of money they have is $75, calculate the loss Cara and Janet will make if they combine their money to buy oranges and sell them at 80% of the buying price.
A: The sum of the ratios representing the amount of money the three has is 4 + 5 + 6 = 15. If the total amount of money they have is $75, the amount of money Cara has represented by the fraction 4 / 15 is 4 / 15 * $75 = $20. Similarly, the amount of money Janet has represented by the fraction 5 / 15 of the total ratio is 5 / 15 * $75 = $25. Combined, Cara and Janet have $20 + 25 = $45. If Cara and Janet buy goods worth $45 and sells them at 80% of the buying price, the selling price of the goods will be 80 / 100 * $45 = $36. Since they bought the goods at $45 and sold them at $36, Janet and Cara would run at a loss of $45 - $36 = $9. The answer is 9.

Q: A Moroccan restaurant received 3 different shipments of couscous. The first two shipments of 7 and 13 pounds arrived on the same day. The next day's shipment was 45 pounds of couscous. If it takes 5 pounds of couscous to make a dish, how many dishes did the restaurant make?
A: The first two shipments of couscous added up to 7 + 13 = 20 pounds. Adding that weight to the next day's shipment results in a total weight of 20 + 45 = 65 pounds. Since each dish takes 5 pounds, then the restaurant makes 65 / 5 = 13 dishes. The answer is 13.
