[Question]A department store offers a 10% discount for the amount exceeding $100 of the customer's total charge. Jaco bought a pair of shoes for $74; 2 pairs of socks that cost $2 per pair; a bag that costs $42. How much will Jaco pay for those items?
[Answer]Two pairs of socks cost $2 x 2 = $4. Jaco's total charge is $74 + $4 + $42 = $120. The amount that exceeds $100 is $120 - $100 = $20. So, Jaco has $20 x 10 / 100 = $2 discount. Therefore, Jaco will pay $120 - $2 = $118 for those items. The answer is 118.
Q: Rubble has $15 in his pocket and he needs to buy 2 notebooks and 2 pens. Each notebook cost $4.00 meanwhile each pen cost $1.50. How much money will be left from Rubble after the purchase?
A: The total cost of two notebooks is $4.00 x 2 = $8.00. The total cost of two pen $1.50 x 2 = $3.00. So, the total amount Rubble spent for all the stuff was $8.00 + $3.00 = $11.00. Therefore, Rubble was left off with $15.00 - $11.00 = $4.00. The answer is 4.
Question: Hadassah took six hours to paint 12 paintings. What would be the total time she's taken to finish all the paintings if she paints 20 more paintings?
Answer: If it took Hadassah six hours to paint 12 paintings, then she paints 12 / 6 = 2 paintings in an hour. If two paintings take an hour to complete, 20 paintings will take 20 / 2 = 10 hours. The total time she took to finish all the paintings is 10 + 6 = 16 hours. The answer is 16.
[Question]Mary is making a model sailboat. She wants to add three sails: a rectangular sail that measures 5 inches by 8 inches and two right triangular sails, one that's 3 inches long at the bottom and 4 inches tall and one that's 4 inches long at the bottom and 6 inches tall. (Remember you can find the area of a triangle by dividing the area of a square with the same height and length by 2). How many square inches of canvas does she need total?
[Answer]First find the area of the square sail: 5 inches * 8 inches = 40 square inches. Then find the area of a square sail with the same height and length as the first triangular sail: 3 inches * 4 inches = 12 square inches. Then divide the area in two to find the area of the triangular sail: 12 square inches / 2 = 6 square inches. Then find the area of a square sail with the same height and length as the second triangular sail: 4 inches * 6 inches = 24 square inches. Then divide the area in two to find the area of the triangular sail: 24 square inches / 2 = 12 square inches. Then add up the areas of all the sails to find the total amount of canvas needed: 12 square inches + 6 square inches + 40 square inches = 58 square inches. The answer is 58.
Q: There were 25 peaches in each basket. Five baskets of peaches were delivered to a market. The farmers have eaten 5 peaches. The remaining peaches are packed into smaller boxes of 15 each. How many boxes of peaches are there?
A: The total number of peaches delivered to a market was 5 x 25 = 125. The remaining peaches after 5 were eaten was 150 - 5 = 145. So, there are 120 / 15 = 8 smaller boxes of peaches. The answer is 8.
Question: Janet buys 3 pounds of broccoli for $4 a pound, 3 oranges for $0.75 each, a cabbage for $3.75, a pound of bacon for $3, and two pounds of chicken for $3 a pound. What percentage of her grocery budget did she spend on meat, rounded to the nearest percent?
Answer:
First find the total cost of the broccoli: 3 pounds * $4 / pound = $12. Then find the total cost of the oranges: 3 oranges * $0.75 / orange = $2.25. Then find the total cost of the vegetables: $12 + $2.25 + $3.75 = $18. Then find the total cost of the chicken: $3 / pound * 2 pounds = $6. Then add the cost of the bacon to find the total cost of the meat: $6 + $3 = $9. Then add the cost of the meat and vegetables to find the total cost of the groceries: $9 + $18 = $27. Then divide the cost of the meat by the total grocery bill and multiply by 100% to express the answer as a percentage: $9 / $27 * 100% = 33.333%, which rounds down to 33%. The answer is 33.
