[Question]Erica is getting dessert at a pie buffet where all the pies are the same size. She takes 1/5 of an apple pie and 3/4 of a cherry pie. What fraction of a whole pie did Erica take, expressed as a percentage?
[Answer]First, find a common denominator for the fractions by multiplying 5 and 4: 5 * 4 = 20. Then convert 1 / 5 to twentieths by multiplying the top and bottom by 4: 1 / 5 * 4 / 4 = 4 / 20. Then convert 3 / 4 to twentieths by multiplying the top and bottom by 5: 3 / 4 * 5 / 5 = 15 / 20. Now that the two fractions have the same denominator, you can add them: 4 / 20 + 15 / 20 = 19 / 20. Now divide 19 by 20 and multiply the answer by 100 to convert the fraction to a percentage: 19 / 20 * 100 = %95. The answer is 95.

[Question]Jonathan enjoys walking and running for exercise, and he has three different exercise routines. On Mondays, he walks at 2 miles per hour. On Wednesdays, he walks at 3 miles per hour. And on Fridays, he runs at 6 miles per hour. On each exercise day, he travels 6 miles. What is the combined total time, in hours, he spends exercising in a week?
[Answer]On Mondays, he walks 6 miles at 2 miles per hour, for a length of 6 / 2 = 3 hours. On Wednesdays, he walks 6 miles at 3 miles per hour, for a length of 6 / 3 = 2 hours. And on Fridays, he runs 6 miles at 6 miles per hour, for a length of 6 / 6 = 1 hour. The combined total time he spends exercising in a week is 3 + 2 + 1 = 6 hours. The answer is 6.

[Question]Princess Daphne bought three necklaces and a set of earrings for a total of $240,000. If all three necklaces were equal in price, and the earrings were three times as expensive as any one necklace, then how expensive was the cost of a single necklace?
[Answer]Let "x" be the price of a single necklace. Thus, the cost of the earrings would be 3x. And since all items totaled $240,000, then x + x + x + 3x = $240,000. Therefore, this simplifies to 6x = 240,000. And, solving for x we see that the price of a single necklace is x = $40,000. The answer is 40000.

[Question]A store gives a 10% discount for the amount of the sell that was over $1000. John buys 7 items that each cost $200. What does his order cost after the discount?
[Answer]
His order came out to 7 * 200 = $1400. So there was 1400 - 1000 = $400 that qualified for the discount. So his discount saved 400 * .1 = $40. So his purchase came out to 1400 - 40 = $1360. The answer is 1360.
