Q: Samir just turned half the age Hania was 10 years ago. If in five years Hania will be 45 years old, what will Samir's age be five years from now?
A: If in five years, Hania will be 45 years old, currently she is 45 - 5 = 40 years old. Ten years ago, Hania was 40 - 10 = 30 years old. Samir just turned half the age Hania was 10 years ago, which means she is 30 / 2 = 15 years old. In five years, Samir will be 15 + 5 = 20 years old. The answer is 20.
Question: Olga has three stripes on the side of each of her tennis shoes. Rick has one less stripe per shoe than does Olga. But Hortense has double the number of stripes on her tennis shoes as does Olga. In total, what is the combined number of stripes on all of their pairs of tennis shoes?
Answer: Rick has one less than three stripes, or 3 - 1 = 2 stripes on each tennis shoe. Hortense has double the 3 stripes that Olga has, or a total of 3 * 2 = 6 stripes per shoe. Since each of them has two tennis shoes per pair, then the total number of stripes on all of their shoes is 2 * (3 + 2 + 6) = 22 stripes. The answer is 22.
[Question]Brittany, Alex, and Jamy all share 600 marbles divided between them in the ratio 3:5:7. If Brittany gives Alex half of her marbles, what's the total number of marbles that Alex has?
[Answer]The total ratio representing the number of marbles is 3 + 5 + 7 = 15. From the ratio, the fraction representing the number of marbles that Brittany has is 3 / 15, which is equal to 3 / 15 * 600 = 120 marbles. Alex has 5 / 15 * 600 = 200 marbles. If Brittany gives half of her marbles to Alex, Alex receives 1 / 2 * 120 = 60 marbles. After receiving 60 marbles from Brittany, Alex has 200 + 60 = 260 marbles. The answer is 260.
Q: Nancy buys 2 coffees a day. She grabs a double espresso for $3.00 every morning. In the afternoon, she grabs an iced coffee for $2.50. After 20 days, how much money has she spent on coffee?
A: She gets a double espresso for $3.00 every morning and an iced coffee for $2.50 in the afternoon so she spends 3 + 2.5 = $5.50 every day on coffee. After 20 days, she spends 20 * 5.5 = $110.00 on coffee. The answer is 110.
Question: Belinda can throw a ball at a speed of 20 feet/second. If the ball flies for 8 seconds before hitting the ground, and Belinda's border collie can run 5 feet/second, how many seconds will it take the border collie to catch up to the ball?
Answer: First find the total distance the ball flies: 20 feet / second * 8 seconds = 160 feet. Then divide that distance by the dog's speed to find how long it takes the dog to catch up to the ball: 160 feet / 5 feet / second = 32 seconds. The answer is 32.
Q: Benny is baking pies for a bake sale. He plans to make ten pumpkin pies, which cost $3 each to make, and twelve cherry pies, which cost $5 each to make. If he wants to make a profit of $20 selling all the pies, how much does he have to charge for each pie if both kinds sell at the same price?
A:
Benny will spend 3 * 10 = $30 to make the pumpkin pies. He will spend 5 * 12 = $60 to make the cherry pies. He wants to make a profit of $20, so he has to earn 30 + 60 + 20 = $110 selling all the pies. He is making 22 pies, so he needs to charge 110 / 22 = $5 per pie. The answer is 5.
