There are 48 crayons in the box. Kiley takes 1/4 of them away. Joe takes away half of the remaining crayons, how many crayons are left?
Step-by-step reasoning process: Kiley takes 48 / 4 = 12 crayons. 48 - 12 = 36 crayons remain. Joe takes 36 / 2 = 18 crayons. 36 - 18 = 18 crayons left.

Answer the following question.
Matt and Tom both walk up the stairs of the library. Matt goes up the stairs 20 steps per minute. Tom goes up the stairs 5 steps per minute more than Matt. If Matt has reached 220 steps above the entrance, how many steps will Tom have gone up by that time?
Step-by-step reasoning process: Matt would have walked for 220 / 20 = 11 minutes. Tom would have gone up by 11 * 5 = 55 steps more. Tom would have gone up by 220 + 55 = 275 steps.
The answer is 275.

Answer the following question.
Sally is selling boxes of crackers for her scout troop's fund-raiser. If she sells 50% more on Sunday than she sold on Saturday, then she'll have sold a total of 150 boxes on the two days. How many boxes did she sell on Saturday?
Step-by-step reasoning process: Let S be the number of boxes sold on Saturday. S + 1.5S = 150. 2.5S = 150. S = 60. Sally sold 60 boxes on Saturday.
The answer is 60.

Answer the following question.
Betty ordered 18 items in an online shop via cash on delivery. She ordered 6 pieces of slippers that cost $2.5 each, 4 pieces of lipstick for $1.25 each, and 8 pieces of hair color for $3 each. How much did Betty pay in total when it was delivered?
Step-by-step reasoning process: Betty paid 6 x $2.5 = $15 for the slippers. She paid 4 x $1.25 = $5 for the lipsticks. She paid 8 x $3 = $24 for the hair color. Therefore, Betty paid $15 + $5 + $24 = $44 in total.
The answer is 44.
