[Question]: Carla's brush is 12 inches long. If Carmen's brush is 50% longer than Carla's brush, how long is Carmen's brush in centimeters? (There are 2.5 centimeters per inch.)
[Answer]: First find the length of Carmen's brush in inches: 150% * 12 inches = 18 inches. Then convert the length from inches to centimeters: 18 inches * 2.5 centimeters / inch = 45 centimeters.
So the answer is 45.

[Question]: There were 63 Easter eggs in the yard. Hannah found twice as many as Helen. How many Easter eggs did Hannah find?
[Answer]: Hannah found twice as many as Helen, so there are 2 + 1 = 3 units of eggs. There were 63 Easter eggs total and there are 3 units of eggs so 63 / 3 = 21 easter eggs per unit. So if Helen found 21 eggs and Hannah found twice as many, then Hannah found 2 * 21 = 42 Easter eggs.
So the answer is 42.

[Question]: Penn operates an ice cream stall for a week. On the first day, she made $10. Every day after that, she made $4 more than the previous day. How much money did Penn make after 5 days?
[Answer]:
On the second day, Penn made $10 + $4 = $14. On the 3rd day, she made $14 + $4 = $18. On the 4th day , she made $18 + $4 = $22. On the 5th day, she made $22 + $4 = $26. After 5 days, Penn made a total of $10 + $14 + $18 + $22 + $26 = $90.
So the answer is 90.
