Q: Jorge and Giuliana each eat 7 croissants for breakfast, 18 cakes after school, and 30 pizzas before bedtime. What is the total number of croissants, cakes, and pizzas the two consume in a day?
A: The number of croissants and cakes that each eats for breakfast and lunch respectively is 7 + 18 = 25. After eating 30 pizzas before bedtime, the number of croissants, cakes, and pizzas that each person have in total for the day is 25 + 30 = 55. Since each person eats a total of 55 croissants, cakes, and pizzas for the day, the two consume a total of 55 + 55 = 110 of the food in a day. The answer is 110.

The sports channels cost $3 less per month than the movie channels. If Jessica adds the movie channels and the sports channels, what will her total monthly payment be?

[Question]When Michelle makes fresh pasta, she first makes the dough, then she rolls it out and cuts it, and then she hangs it on racks to dry for cooking later. She needs a drying rack for each three pounds of pasta she makes, and it takes two cups of flour to make each pound of pasta dough. She owns three racks right now. How many more drying racks will Michelle need if she makes pasta using three 8-cup bags of flour?
[Answer]Michelle used 3 * 8 = 24 cups of flour in the pasta dough. She made 24 / 2 = 12 pounds of pasta dough. She needs 12 / 3 = 4 drying racks for the pasta. Thus, Michelle needs 4 - 3 = 1 more drying rack. The answer is 1.
Q: A truck driver has to spend $2 per gallon of gas. She can drive 10 miles per gallon. She drives at a rate of 30 miles per hour. If she is paid $.50 per mile, how much money does she make if she drives for 10 hours?
A: The truck driver drives for 10 hours at 30 miles per hour, so she drives 10 * 30 = 300 miles. Therefore, she needs 300 / 10 = 30 gallons of gas. This will cost her 30 * $2 = $60. She will make 300 * $.50 = $150. Thus, after paying for gas, she will make $150 - $60 = $90. The answer is 90.

The new camera cost 4000 * .3 = $1200 more than the old camera. So the camera cost 4000 + 1200 = $5200. The lens cost 400 - 200 = $200. So the total cost was 5200 + 200 = $5400. The answer is 5400.
