On our last vacation, I bought 4 times as many tetras as Tim bought clowns. Tim bought twice as many clowns as Rick bought guppies. If Rick bought 30 guppies, how many animals did we buy on our last vacation?
Let's think: If Rick bought 30 guppies, Tim bought 2 clowns / guppy * 30 guppies = 60 clowns. The total number of tetras bought by you is 4 tetras / clown * 60 clowns = 240 tetras. In total, the three bought 240 tetras + 60 clowns + 30 guppies = 330 animals.. The answer is: 330.

It takes 50 minutes to cut a woman's hair, 15 minutes to cut a man's hair, and 25 minutes to cut a kid's hair. If Joe cut 3 women's, 2 men's, and 3 children's hair, how much time did he spend cutting hair?
Let's think: He spent 3 * 50 = 150 minutes cutting women's hair. He spent 2 * 15 = 30 minutes cutting men's hair. He spent 3 * 25 = 75 minutes cutting children's hair. He spent a total of 150 + 30 + 75 = 255 minutes.. The answer is: 255.

Kate has 2 red balloons and 4 blue balloons. Assuming she inflates 4 more balloons, two of each color red and blue, what is the percent likelihood that one selected at random will be red?
Let's think: After inflating the 4 new balloons, she will have 2 red + 4 blue + 4 new = 10 total balloons. The probability of selecting red will be (2 red + 2 red newly inflated) / 10 total balloons = 40%.. The answer is: 40.

There are 50 more pens than notebooks on Wesley's school library shelf. If there are 30 notebooks on the shelf, how many notebooks and pens, does he have altogether?
Let's think:
If there are 30 notebooks on the shelf, there are 50 + 30 = 80 pens on the shelf. Altogether, Wesley has 80 + 30 = 110 notebooks and pens on the shelf.. The answer is: 110.
