[Question]Marissa's sunflower is 21 inches taller than her little sister. If her sister is 4 feet 3 inches tall, how tall is Marissa's sunflower in feet?
[Answer]Since 1 foot is equal to 12 inches, then 4 feet is equal to 4 x 12 = 48 inches. So, Marissa's sister is 48 + 3 = 51 inches tall. The sunflower is 51 + 21 = 72 inches tall. Therefore, the sunflower is 72 / 12 = 6 feet tall. The answer is 6.
Q: Lauren wanted to make burgers and fries for dinner. She needed a few things from the grocery store and bought the following: 2 pounds of hamburger meat that was on sale for $3.50 a pound. 1 pack of hamburger buns for $1.50. A head of lettuce for $1.00 and a large 1.5-pound tomato that was priced at $2.00 per pound. She also needed a jar of pickles that cost $2.50 and she had a $1.00 off coupon for that item. How much change would Lauren get back if she paid with a $20 bill?
A: She bought 2 pounds of hamburger meat at $3.50 per pound so 2 * 3.50 = $7.00. The tomato weighed 1.5 pounds and cost $2.00 per pound so 1.5 * 2 = $3.00. When you add up all her items she spent 7 + 1.50 + 1 + 3 + 2.50 = $15.00. Her items added up to $15.00 and she had a $1.00 coupon off pickles so 15 - 1 = $14.00. She paid with a $20.00 bill so 20 - 14 = $6.00 in change. The answer is 6.
Question: Bill needs to soak his clothes for 4 minutes to get rid of each grass stain and 7 additional minutes to get rid of each marinara stain. If his clothes have 3 grass stains and 1 marinara stain, how long does he need to soak them?
Answer: First find the total soaking time to get rid of the grass stains: 4 minutes / stain * 3 stains = 12 minutes. Then add the soak time for the marinara to find the total soak time: 12 minutes + 7 minutes = 19 minutes. The answer is 19.
[Question]If the price of a bag of cherries is $5 when the price of a bag of olives is $7, how much would Jordyn pay for buying 50 bags of each fruit and a 10% discount?
[Answer]At a 10 percent discount, Jordyn will pay 10 / 100% * $5 = $.50 less for a bag of cherries. To buy one of the cherries at a 10% discount Jordyn will pay $5 - $0.50 = $4.50. The cost of buying 50 bags of cherries at the 10% discount is 50 * 4.50 = $225. Also, at a 10% discount, Jordyn will pay 10 / 100 * $7 = $0.70 less for a bag of olives. The price of a bag of olives at a 10% discount is $7 - $0.70 = $6.3. To buy 50 bags of olives Jordyn will pay $6.3 * 50 = $315. The total cost of buying 50 bags of each fruit at a 10% discount is $315 + $225 = $540. The answer is 540.
Q: Mary, Jess, and Christina want to decorate a party room with balloons. Each person inflates balloons at different speeds, and they only have 30 minutes to inflate as many balloons as possible. Mary inflates 10 balloons per minute, Jess inflates 7 balloons per minute and Christina came 15 minutes late and was the slowest one inflating 4 balloons per minute. How many balloons can they inflate before running out of time?
A: Mary will inflate a total of 10 balloons / minute x 30 minutes = 300 balloons. Jess will inflate a total of 7 balloons / minute x 30 minutes = 210 balloons. Christina will inflate a total of 4 balloons / minute x 15 minutes = 60 balloons. Combining all balloons, they made 300 balloons + 210 balloons + 60 balloons = 570 balloons. The answer is 570.
Question: Bertha plays tennis. Every ten games, one of her tennis balls wears out. Every five games, she loses a ball. Every four games, she buys a canister of three balls. She started with two balls and gave one to her partner. After twenty games, how many tennis balls does she have?
Answer:
Bertha wears out 20 / 10 = 2 tennis balls in 20 games. She loses 20 / 5 = 4 tennis balls in 20 games. She buys canisters of 3 * 20 / 4 = 15 tennis balls in 20 games. Bertha started with 2 balls and gave 1 away, so she has 2 + 15 - 2 - 4 - 1 = 10 tennis balls after twenty games. The answer is 10.
