Answer the following question.
John uses a 75-watt electric fan for 8 hours a day. How much kWh of electric energy does he consume per month (30 days) for using the electric fan?
Step-by-step reasoning process: In a day, John uses 75x 8 = 600 watts. So in a month, he uses 600 x 30 = 18 000 watts. Since there are 1000 watts in 1 kilowatt, then John uses 18000 / 1000 = 18.
The answer is 18.

Answer the following question.
Shannon bought 5 pints of frozen yogurt, two packs of chewing gum, and five trays of jumbo shrimp from The Food Place for a total of $55 If the price of a tray of jumbo shrimp is $5 and a pack of chewing gum costs half as much as a pint of frozen yogurt, what is the price of a pint of frozen yogurt?
Step-by-step reasoning process: 5 trays of jumbo shrimp cost 5 x 5 = $25. 5 pints of frozen yogurt and 2 packs of gum in total cost 55 - 25 = $30. 2 packs of gum cost as much 2 / 2 = 1 pint of frozen yogurt. Therefore 5 + 1 = 6 pints of frozen yogurt costs $30. A pint of frozen yogurt costs 30 / 6 = $5.
The answer is 5.

Answer the following question.
A movie theater company is advertising a deal of a movie ticket, a bucket of popcorn, a drink, and a box of candy for $20. Normally, a movie ticket costs $8, a bucket of popcorn costs three dollars less, a drink costs a dollar more than popcorn, and a candy costs half as much as a drink. How many dollars does the deal save a customer who buys a ticket, popcorn, drink, and candy normally?
Step-by-step reasoning process: The popcorn costs 8 - 3 = $5. The drink costs 5 + 1 = $6. The candy costs 6 / 2 = $3. The normal price is 8 + 5 + 6 + 3 = $22. Thus, the deal saves a customer 22 - 20 = $2.
The answer is 2.
