Question: Jenna is adding black dots to a bunch of white blouses. Each blouse gets 20 dots, and each dot takes 10 ml of black dye. How many 400-ml bottles of dye does Jenna need to buy to dye 100 blouses?
Answer: First find the amount of dye each blouse takes: 20 dots / blouse * 10 ml / dot = 200 ml / blouse. Then multiply the dye used per blouse by the number of blouses to find the total amount of dye used: 200 ml / blouse * 100 blouses = 20000 ml. Then divide the amount of dye needed by the amount of dye per bottle to find the number of bottles needed: 20000 ml / 400 ml / bottle = 50 bottles. The answer is 50.
[Question]A bag was originally priced at $500. A week after, the price was reduced by 5%. Since the bag was still not sold, the selling price was reduced by 4% a month after. How much was the total reduction from the original selling price?
[Answer]The original price of the bag was reduced by $500 x 5 / 100 = $25. So its selling price after a week was $500 - $25 = $475. The price of the bag was again reduced by $475 x 4 / 100 = $19. So, its selling price now is $475 - $19 = $456. Therefore, the total reduction from the selling price is $500 - $456 = $44. The answer is 44.
[Question]Val cuts a single watermelon into 40 slices, and each slice has 20 black seeds and 20 white seeds. What is the total number of seeds in a watermelon?
[Answer]
40 slices per watermelon and each slice having 20 black seeds means each watermelon has 20 * 40 = 800 black seeds. 40 slices per watermelon and each slice having 20 white seeds means each watermelon has 20 * 40 = 800 white seeds. In total, each watermelon has 800 + 800 = 1600 seeds. What is the total number of seeds in a watermelon?. The answer is 1600.
