Question: Buffy and Oz went to dinner. They shared an appetizer that cost $9.00. Each of their entrees was $20.00 and they shared a dessert that was $11.00. If they left a 30% tip, what was the entire price of the meal?
Answer: Step-by-step reasoning process: Each of their entrees cost $20.00 so they cost 2 * 20 = $40.00. The appetizer was $9.00, the main meal was $40.00 and the dessert was $11.00 for a total of $60.00. The entire meal cost $60.00 and they left a 30% tip which came to 60 * .30 = $18.00. The meal was $60.00 and the tip was $18.00 so the total bill came to 60 + 18 = $78.00.
So the answer is 78.

Question: Reyna had 20 lamps with seven light bulbs in each lamp. If 1/4 of them have 2 burnt-out light bulbs each, how many light bulbs are working?
Answer: Step-by-step reasoning process: The total number of light bulbs in the 20 lamps is 20 * 7 = 140. If 1 / 4 of the 20 lamps have burnt - out light bulbs, there are 1 / 4 * 20 = 5 lamps with burn out light bulbs. Since each of the 5 lamps has 2 burnt - out light bulbs, the number of burn out light bulbs is 2 * 5 = 10. The number of working light bulbs is 140 - 10 = 130.
So the answer is 130.

Question: Camp Cedar has 40 boys, it has 3 times as many girls. It needs 1 counselor for every 8 children. How many counselors does Camp Cedar need?
Answer: Step-by-step reasoning process: Camp has 3 * 40 boys = 120 girls. Camp Cedar has a total of 40 boys + 120 girls = 160 children. Camp needs 1 counselor per 8 children, so 160 children / 8 children = 20 counselors needed.
So the answer is 20.

Question: Elijah is painting his living room and decides to buy masking tape to make his painting neater. 2 of his walls are 4 meters wide and the other 2 walls are 6 meters wide. Elijah needs enough masking tape to cover the entire width of each wall and can order the exact amount of masking tape he needs. How many meters of masking tape does Elijah need to order?
Answer:
Step-by-step reasoning process: For 2 of the walls, Elijah will need 2 walls * 6 meters each = 12 meters of masking tape. For the other 2 walls, he will need 2 walls * 4 meters each = 8 meters of masking tape. He will therefore need a total of 12 + 8 = 20 meters of masking tape.
So the answer is 20.
