[Question]Ken buys gummy vitamins. They are usually $15.00 per bottle at his grocery store, but they are currently 20% off. On top of that, he has 3 $2.00 coupons. How much will 3 bottles cost?
[Answer]The vitamins are $15.00 a bottle and are currently 20% off so that’s 15 * .20 = $3.00 off. The vitamins are $15.00 and they are $3.00 off so they are now 15.00 - 3 = $12.00. He has 3 $2.00 coupons so that’s 3 * 2 = $6.00 in coupons. He buys 3 bottles at $12.00 each so that’s 3 * 12 = $36.00. He has $6.00 in coupons so his vitamins will now costs 36 - 6 = $30.00. The answer is 30.
Q: During a soccer game, in the first half, Team A scored 8 points, and Team B scored only half as many points. In the second half, Team B was able to get as many points as Team A in the first half, and Team A scored only 2 goals less than Team B. How many goals did both teams score during the whole match?
A: During the first half Team, B scored only 8 * 0.5 = 4 points. In the second half Team A scored 2 goals less than Team B, so they scored 8 - 2 = 6 points. So in total both teams scored 8 + 4 + 6 + 8 = 26 points. The answer is 26.
Question: Sidney has 4 kittens and 3 adult cats. She has 7 cans of cat food. Each adult cat eats 1 can of food per day. Each kitten eats 3/4 of a can per day. How many additional cans of food does Sidney need to buy to feed all of her animals for 7 days.
Answer: Sidney has 3 adult cats * 1 can of food = 3 cans of food per day. Sidney's adult cats will need 3 cans * 7 days = 21 cans for the week. Sidney has 4 kittens * 3 / 4 cup of food = 3 cans of food per day. Sidney's kittens will need 3 cans * 7 days = 21 cans for the week. Sidney will need to buy 21 cans + 21 cans - 7 cans = 35 cans. The answer is 35.
[Question]Ravi can jump higher than anyone in the class. In fact, he can jump 1.5 times higher than the average jump of the three next highest jumpers. If the three next highest jumpers can jump 23 inches, 27 inches, and 28 inches, how high can Ravi jump?
[Answer]The total height the next three highest can jump is 78 inches because 23 + 27 + 28 = 78. The average height they can jump is 26 inches because 78 / 3 = 26. Ravi can jump 39 inches high because 26 x 1.5 = 39. The answer is 39.
