Question: Oliver is trying to decide between two different sized boxes of macaroni and cheese. He wants to know which is the better value, so instead of just looking at the overall price, he looks at the price per ounce. The larger box is 30 ounces and the smaller box is 20 ounces. The larger box costs $4.80. The smaller box costs $3.40. What is the price per ounce in cents of the box with the better value (lowest price per ounce)?
Answer: The larger box of macaroni and cheese costs 480 cents / 30 ounces = 16 cents per ounce. The smaller box of macaroni and cheese costs 340 cents / 20 ounces = 17 cents per ounce. The lower price per ounce is 16 cents. The answer is 16.

Q: Annie is trying to figure out whether it's safe to drive her truck. For every 3 degrees the temperature drops below 32 degrees, Annie's chances of skidding on ice increase 5%. If she goes into a skid, she has a 40% of regaining control. Otherwise, she'll have a serious accident. If the temperature is 8 degrees, what is the percentage chance of Annie getting into a serious accident if she drives?
A: First find how many degrees below 32 the temperature is: 32 degrees - 8 degrees = 24 degrees. Then divide that amount by the number of degrees per 5% increase in skid risk to find how many 5% increases there are: 24 degrees / 3 degrees / 5% increase = 8 5% increases. Multiply the number of increases by 5% to find the total increase in skid risk: 8 * 5% = 40%. Now find the chance that Annie has a serious accident if she goes into a skid by subtracting the chance she regains control from 100%: 100% - 40% = 60%. Finally, multiply the chance of going into a skid by the chance of having a serious accident after a skid to find the total risk of a serious accident: 60% * 40% = 24%. The answer is 24.
Question: James had two browsers on his computer. In each browser, he opened three windows, each with ten tabs. What's the total number of tabs he opened in all the browsers together?
Answer: The total number of tabs in three windows of each browser is 10 * 3 = 30 tabs. If James had two browsers on his computer and in each browser he opened three windows, the total number of tabs in the two browsers is 2 * 30 = 60 tabs. The answer is 60.
