Question: The kids in Ms. Swanson's class have an average of 5 zits each. The kids in Mr. Jones' class have an average of six zits each. If there are 25 kids in Ms. Swanson's class and 32 in Mr. Jones' class, how many more zits are there in Mr. Jones' class than in Ms. Swanson's?
Answer with step-by-step thinking: First find the total number of zits in Mr. Jones' class: 6 zits / kid * 32 kids = 192 zits. Then find the total number of zits in Ms. Swanson's class: 5 zits / kid * 25 kids = 125 zits. Then subtract the number of zits in Ms. Swanson's class from the number in Mr. Jones' class to find the difference: 192 zits - 125 zits = 67 zits.
So the answer is 67.


Question: John attends a protest for 4 days. He then attends a second protest for 25% longer than the first. How many days did he spend protesting?
Answer with step-by-step thinking: The second protest was 4 * .25 = 1 day longer than the first. So the second protest was 4 + 1 = 5 days. Thus he spent 4 + 5 = 9 days protesting.
So the answer is 9.

After spending money on a shirt, Lily had $55 - $7 = $48 left. She spent $7 x 3 = $21 on another store. Therefore, she only has $48 - $21 = $27 left on her account.
So the answer is 27.
