[Question]Linda is repainting her bedroom. The wall area is 600 sq. ft. If a gallon of paint can cover 400 sq. ft., how many gallon cans of paint will Linda have to buy if she wants to do two coats?
[Answer]Linda wants to do two coats, so the total area she will be painting is 2 coats * 600 sq. ft. / coat = 1200 sq. ft. A gallon of paint will cover 400 sq. ft., so Linda will need 1200 sq. ft. / 400 sq. ft. per can = 3 cans of paint. The answer is 3.
Q: Solomon bought a dining table at a 10% discount and paid the sale price of $450. What was the original price of the dining table?
A: Since there was a 10% discount, this means that Solomon only paid 100% - 10% = 90% of the original price. The 90% is represented by $450, so 1% is equal to $450 / 90 = $5. Therefore, the original price of the dining table is $5 x 100 = $500. The answer is 500.
Question: Mark bought a shirt, pants, and shoes for $340. What is the price of the pants knowing that the price of a shirt is three-quarters of the price of the pants and that the price of a shoe is ten dollars more than the price of the pants?
Answer: Let X be the price of the pants. The price of the shirt is 3 / 4 * X. The price of the shoes is X + 10. The total amount paid is X + 3 / 4 * X + X + 10 = $340. Combining like terms we get X * 11 / 4 + 10 = $340. Subtracting 10 from both sides we get X * 11 / 4 = $330. Dividing both sides by 11 / 4 we get X = $120. The answer is 120.
[Question]Jacob's water tank can hold up to 50 liters of water. Jacob collects water from the river and rain to fill his water tank. He can collect 800 milliliters of water from the rain and 1700 milliliters of water from the river every day. How many days does Jacob need to fill up his water tank?
[Answer]Jacob collects 800 + 1700 = 2500 milliliters of water from the river and rain every day. Since 1 liter is equal to 1000 milliliters, then 50 liters is equal to 50x1000 = 50,000 milliliters of water. Therefore Jacob needs 50,000 / 2500 = 20 days to fill his water tank. The answer is 20.
[Question]Adam bought 15 apples on Monday. On Tuesday he bought 3 times that quantity. On Wednesday he bought 4 times the quantity he bought on Tuesday. What is the total quantity Adam bought on these three days?
[Answer]
On Tuesday, Adam bought 3 * 15 apples = 45 apples. On Wednesday, Adam bought 4 * 45 apples = 180 apples. Adam bought 15 apples + 45 apples + 180 apples = 240 apples on the three days. The answer is 240.
