Question: At Theo’s cafe, he makes 3 egg and 4 egg omelettes. His cafe is open from 7:00 a.m. to 11:00 a.m. In the first hour, 5 customers order the 3 egg omelettes. In the second hour, 7 customers order the 4 egg omelettes. In the third hour, 3 customers order the 3 egg omelettes. In the last hour, 8 customers order the 4 egg omelettes. How many eggs does Theo need to make all the omelettes?
Answer: Step-by-step reasoning process: In the first and third hour, 5 + 3 = 8 customers order the 3 egg omelettes. In the second and last hour, 7 + 8 = 15 customers order the 4 egg omelettes. To make the 3 egg omelettes, Theo needs 3 x 8 = 24 eggs. To make the 4 egg omelettes, Theo needs 15 x 4 = 60 eggs. To make all the omelettes, he needs 24 + 60 = 84 eggs.
So the answer is 84.

Question: Janet buys 45-pound containers of cat litter for $21 each. If her cat litter box holds 15 pounds of cat litter, and she changes out the litter weekly, how much will it cost, in dollars, for her to buy enough litter to last 210 days?
Answer:
Step-by-step reasoning process: If she changes the box weekly, then in 210 days, she will change the box 210 / 7 = 30 times. At 15 pounds of litter for every box change, she will require 30 * 15 = 450 pounds of cat litter in 210 days. If she buys 45 - pound containers, then for 450 pounds she will need to buy 450 / 45 = 10 containers of litter. At $21 per container, to buy enough cat litter for 210 days, it will cost 10 * $21 = $210.
So the answer is 210.
