Q: Eliza has 4 siblings. The total height of all 5 siblings combined is 330 inches. Two of her siblings are both 66 inches tall. Another sibling is 60 inches tall. If Eliza is 2 inches shorter than the last sibling, how tall is Eliza?
A: The first three siblings are 66 + 66 + 60 = 192 inches tall. Since the total of all the siblings is 330 inches, Eliza and the last sibling are 330 - 192 = 138 inches tall combined. If Eliza's height = h, 138 inches = h + (h + 2). (138 - 2) / 2 = 68 inches. Eliza is 68 inches tall. The answer is 68.

Q: Tim's website got 100 visitors a day for the first 6 days and then on the last day of the week it got twice as many visitors as every other day combined. If he gets $.01 per visit how much did he make that week?
A: In the first 6 days, he got 6 * 100 = 600 visits. So on the 7th day, he got 600 * 2 = 1200 visitors. So he got a total of 1200 + 600 = 1800 visitors. That means he made 1800 * .01 = $18. The answer is 18.

Q: Perry, Dana, Charlie, and Phil played golf together every week. At the end of the season, Perry had won five more games than Dana, but Charlie had won 2 games fewer than Dana. Phil had won 3 games more than Charlie did. If Phil won a total of 12 games, how many more games did Perry win than did Phil?
A:
If Phil had won 3 games more than did Charlie, and Phil won 12 games, then Charlie won 12 - 3 = 9 games. If Charlie had won 2 games fewer than Dana, and Charlie won 9 games, then Dana won 9 + 2 = 11 games. If Perry had won five more games than did Dana, and Dana won 11 games, then Perry won 11 + 5 = 16 games. Thus, Perry won 16 - 12 = 4 more games than did Phil. The answer is 4.
