[Question]John has started at a job he works every day 10 days ago. So far, he's made $250. How many more days must John work before he makes twice this amount, assuming he makes the same amount every day?
[Answer]John has made $250 in 10 days, so this means he makes $250 / 10 = 25 dollars a day. Since John wants to make double his current amount, this means he wants to make 250 * 2 = 500 dollars. This means John needs to work 500 / 25 = 20 days in total to make 500. As John has already worked 10 days, this means he needs to work 20 - 10 = 10 more days to make his goal. The answer is 10.

[Question]Vivi bought fabric to make new pillows for her bed. She spent $75 on checkered fabric and $45 on plain fabric. If both fabrics cost $7.50 per yard, how many total yards of fabric did she buy?
[Answer]The total yards of the checkered fabric is $75 / 7.50 = 10. The total yards of the plain fabric is 45 / 7.50 = 6. So, Vivi bought a total of 10 + 6 = 16 yards of fabric. The answer is 16.
