[Question]A restaurant makes 40 more pizzas than hot dogs every day. If the restaurant makes 60 hot dogs every day, how many pizzas and hot dogs will it make in June?
[Answer]If the restaurant makes 60 hot dogs and 40 more pizzas than hot dogs every day, it makes 60 + 40 = 100 pizzas. The total number of pizzas and hot dogs it makes in a day is 100 + 60 = 160. In June, with thirty days, the restaurant will make 30 * 160 = 4800 pizzas and hot dogs in total. The answer is 4800.

[Question]There are 180 students in ninth grade. 1/4 of them bombed their finals because they were going through difficult breakups. 1/3rd of the rest didn't show up to take the test, and another 20 got less than a D. How many students passed their finals?
[Answer]First find the number of students who went through breakups: 1 / 4 * 180 = 45 students. Then subtract that number from the total number: 180 students - 45 students = 135 students. Then divide that number by 3 to find the number of students who didn't show up to take the test: 135 students / 3 = 45 students. Then subtract the number of students who failed in each way from the total number to find the number who passed: 180 students - 45 students - 45 students - 20 students = 70 students. The answer is 70.
