Question: Nina enjoys keeping insects as pets. She has 3 spiders and 50 ants. Each spider has 8 eyes. Each ant has 2 eyes. How many eyes are there in total among Nina’s pet insects?
Answer: The number of eyes from the spiders is 3 * 8 = 24 eyes. The number of eyes from the ants is 50 * 2 = 100 eyes. The total number of eyes among Nina’s insects is 24 + 100 = 124 eyes. The answer is 124.

Question: At the museum, Bethany saw 4 times more still lifes than portraits. If she saw 80 paintings total, how many portraits did she see?
Answer: Let s be the number of still lifes Bethany saw and p be the number of portraits. We know that s + p = 80 and s = 4p. Substituting the second equation into the first equation, we get 4p + p = 80. Combining like terms, we get 5p = 80. Dividing both sides by 5, we get p = 16. The answer is 16.

Question: Mike is 16 years old. His sister Barbara is half as old as he is. How old is Barbara going to be when Mike is 24 years old?
Answer: Barbara is currently 16 years / 2 = 8 years old. Mike is going to be 24 years old after 24 years - 16 years = 8 years. So Barbara is going to be 8 years + 8 years = 16 years old. The answer is 16.

Question: A type C school bus contains 13 rows of seats, with an aisle running down the middle of the bus, splitting each row into two sections. If the school only allowed two students to sit in each section, how many students could be seated on the bus?
