Answer the following 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?
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.
The answer is 84.

Answer the following question.
A global gym decides to replace all of its cardio machines. They have 20 gyms. Each gym has 10 bikes, 5 treadmills, and 5 elliptical machines. The bikes cost $700 each. The treadmills cost 50% more than that. The elliptical machines are twice as expensive as the treadmills. How much does it cost to replace everything?
Step-by-step reasoning process: The gym needs to buy 20 * 10 = 200 bikes. 20 * 5 = 100 each of treadmills and ellipticals. So the bikes cost 200 * 700 = $140,000. The treadmills cost 700 * 1.5 = $1,050 each. So they cost a total of 1050 * 100 = $105,000. The ellipticals each cost 1050 * 2 = $2100. So in total the ellipticals cost 2100 * 100 = $210,000. So the total cost of everything is 140,000 + 105,000 + 210,000 = $455,000.
The answer is 455000.

Answer the following question.
Bran's tuition fee is $90. He does a part-time job that pays him $15 per month and he has a scholarship that takes care of 30% of his tuition fee. If he needs to pay his tuition fee within 3 months, how much does Bran still need to pay?
Step-by-step reasoning process: Bran's scholarship pays $90 x 0.30 = $27 to his tuition fee. So, the total amount he still needs to pay is $90 - $27 = $63. And Bran will be able to earn $15 x 3 = $45 after working for 3 months. Therefore, the total amount he still needs to pay is $63 - $45 = $18.
The answer is 18.
