We harvested 405 kg of apples. 90 kg were used to make fruit juice and 60 kg were given to a restaurant. The rest was sold in 5 kg bags and their sale brought in $408. What was the selling price of one bag of apples?
Let's think: The weight of apples used for juice and given to the restaurant is 60 + 90 = 150 kg. Thus 405 150 = 255kg worth of apples were sold in 5 kg bags. There were 255 / 5 = 51 bags sold. So each bag was sold for 408 / 51 = $8.. The answer is: 8.

The cash price of a refrigerator was $8000. Samantha wanted to buy the refrigerator but pay in installments. If she paid a deposit of $3000 and paid 30 equal monthly installments of $300 each, calculate how much money she would have saved by paying cash.
Let's think: When Samantha paid $300 in 30 equal monthly installments, she paid a total of $9000. Since the higher purchase is a deposit plus the total monthly installments, Samatha paid $3000 + $9000 = $12000 for the refrigerator on higher purchase. If she would have bought the refrigerator on the cash prize, Samantha would have paid $12000 - to $8000 = $4000 less.. The answer is: 4000.

Vicente bought 5 kilograms of rice and 3 pounds of meat. Each kilogram of rice is $2 and a pound of meat is $5. How much did Vicente spend in total?
Let's think: Vicente spent 5 x $2 = $10 for 5 kilograms of rice. He spent 3 x $5 = $15 for 3 pounds of meat. Therefore, the total amount he spent was $15 + $10 = $25.. The answer is: 25.

Erin works in the school cafeteria serving soup. Each bowl of soup has 10 ounces, and Erin can serve 5 bowls per minute. If the pot of soup has 6 gallons of soup, how long will it take Erin to serve all the soup, rounded to the nearest minute? (There are 128 ounces to a gallon.)
Let's think:
First find the number of ounces Erin serves per minute: 10 ounces / bowl * 5 bowls / minute = 50 ounces / minute. Then find the number of ounces in the pot: 6 gallons * 128 ounces / gallon = 768 ounces. Then divide the total amount of soup by the amount of soup Erin serves per minute: 768 minutes / 50 ounces / minute = 15.36 minutes, which rounds down to 15 minutes.. The answer is: 15.
