[Question]: Tom went to the store to buy fruit. Lemons cost $2, papayas cost $1, and mangos cost $4. For every 4 fruits that customers buy, the store offers a $1 discount. Tom buys 6 lemons, 4 papayas, and 2 mangos. How much will he pay?
[Answer]: For 6 lemons, Tom will pay 6 * 2 = $12. For 3 papayas, he will pay 3 * 1 = $3. For 2 mangos, he will pay 2 * 4 = $8. In total, the cost of the fruits before discount is 12 + 4 + 8 = $24. The total number of fruits is 6 + 4 + 2 = 12 fruits. For 12 fruits, Tom gets a discount of 12 / 4 = $3. Subtracting the discount offered by the store, Tom will pay 24 - 3 = $21.
So the answer is 21.

[Question]: 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?
[Answer]: Kiley takes 48 / 4 = 12 crayons. 48 - 12 = 36 crayons remain. Joe takes 36 / 2 = 18 crayons. 36 - 18 = 18 crayons left.
So the answer is 18.

[Question]: Jackie walks 2 miles each day while Jessie walks 1.5 miles each day. How many more miles, in all, does Jackie walk than Jessie walk in 6 days?
[Answer]:
Jackie walks 2 - 1.5 = 0.5 miles more each day than Jessie. So in 6 days, Jakie walks 0.5 x 6 = 3 miles more than Jessie.
So the answer is 3.
