[Question]: Big Lots is having a sale. All chairs are 25% off. If you buy more than 5 chairs, you get an additional 1/3 off the discounted price of the number of chairs over 5. If you bought 8 chairs that were normally priced at $20, how much do the chairs cost in total?
[Answer]: You save $5 per chair with the 25% off sale. On sale chairs cost $15 each because 20 - 5 = 15. You bought 3 chairs above the 5 required before the extra savings starts because 8 - 5 = 3. You save an extra $5 on these chairs because 15 x (1 / 3) = 5. The first five chairs cost $75 in total because 5 x 15 = 75. The final three chairs cost $30 in total because 3 x 10 = 30. In total they cost $105 because 75 + 30 = 105.
So the answer is 105.

[Question]: Vicente bought 5 kilograms of rice and 3 pounds of meat. Each kilogram of rice is $2 and a pound of meat is $5. How much did Vicente spend in total?
[Answer]: Vicente spent 5 x $2 = $10 for 5 kilograms of rice. He spent 3 x $5 = $15 for 3 pounds of meat. Therefore, the total amount he spent was $15 + $10 = $25.
So the answer is 25.

[Question]: 3/5 of the mangoes on a mango tree are ripe. If Lindsay eats 60% of the ripe mangoes, calculate the number of ripe mangoes remaining if there were 400 mangoes on the tree to start with.
[Answer]:
The number of ripe mangoes from the tree is 3 / 5 * 400 = 240. If Lindsay eats 60% of the ripe mangoes, she eats 60 / 100 * 240 = 144 mangoes. The total number of ripe mangoes remaining is 240 - 144 = 96.
So the answer is 96.
