Jill is painting her 20 toenails and fingernails. She paints 6 of her nails purple, 8 of them blue, and the rest striped. What is the difference in percentage points between the percentage of nails painted blue and the percentage painted striped?
Let's think: First find the total number of striped nails: 20 nails - 6 nails - 8 nails = 6 nails. Then divide the number of blue nails by the number of total nails and multiply by 100% to express the answer as a percentage: 8 blue nails / 20 total nails * 100% = 40%. Then divide the number of striped nails by the number of total nails and multiply by 100% to express the answer as a percentage: 6 striped nails / 20 total nails * 100% = 30%. Then subtract the percentage of striped nails from the percentage of blue nails to find the difference: 40% - 30% = 10%.. The answer is: 10.

James hires a seamstress to fix all his shirts and pants. He has 10 shirts and 12 pairs of pants. It takes 1.5 hours to fix a shirt and twice as long for pants. The tailor charges $30 per hour. How much does it cost?
Let's think: It takes 10 * 1.5 = 15 hours to fix his shirts. It takes 1.5 * 2 = 3 hours per pair of pants. So it takes 3 * 12 = 36 hours for the pants. That means in total it takes 15 + 36 = 51 hours. So it cost 51 * 30 = $1530 to fix everything.. The answer is: 1530.

A watermelon weighs 23 pounds. If Farmer Kent sells his special watermelons for $2 a pound, how much money would he make for selling 18 watermelons of the same weight?
Let's think: A single watermelon would sell for $2 x 23 = $46. 60 watermelons would sell for $46 x 18 = $828.. The answer is: 828.

There are 16 people at a dinner party. There are 40 dinner rolls available for them. Half the people eat 1 1/2 rolls each. The other half eat 1/2 a roll each. How many dinner rolls are leftover?
Let's think:
Half the people at the party is 16 / 2 = 8 people. 8 people at the party eat 1 1 / 2 rolls each, 8 x 1 1 / 2 = 12 dinner rolls eaten. 8 people at the party eat 1 / 2 a roll each, 8 x 1 / 2 = 4 dinner rolls eaten. Combined, the people at the party ate 12 + 4 = 16 dinner rolls. There were originally 40 dinner rolls - 16 that got eaten = 24 dinner rolls leftover.. The answer is: 24.
