[Question]Sara and Joe have a combined height of 120 inches. Joe is 6 inches more than double Sara's height. How tall is Joe?
[Answer]Let x be Sara's height in inches. Joe is 6 + 2x inches tall. 120 = x + (6 + 2x). 120 = 3x + 6. 114 = 3x. x = 38 inches. Joe is 6 + 2(38) = 82 inches. The answer is 82.
Q: Joanne makes $16.00 working at her main job for 8 hours a day. She has a part-time job, working an extra 2 hours a day where she makes $13.50 an hour. How much money does she make if she works this schedule 5 days a week?
A: She works 8 hours a day at $16.00 an hour so she makes 8 * 16 = $128.00 a day. She works this job 5 days a week so she makes 128 * 5 = $640.00 in 5 days. She works 2 hours a day at $13.50 an hour so she makes 2 * 13.50 = $27.00 a day. She works this job 5 days a week so she makes 27 * 5 = $135.00. She makes $640 at her main job and $135 at her part - time job so all total she makes 640 + 135 = $775.00 in 5 days. The answer is 775.
Question: Samantha sleeps an average of 8 hours a night. Her baby sister sleeps 2.5 times as much as Samantha does. Because her father is so tired from watching the baby, for every hour the baby sleeps, he sleeps 30 minutes. How many hours does her father sleep in a week?
Answer: The baby sleeps 20 hours a day because 2.5 x 8 = 20. The baby sleeps 2 times as much as the father because 60 / 30 = 2. The father sleeps 10 hours a night because 20 / 2 = 10. The father sleeps for 70 hours a week because 7 x 10 = 70. The answer is 70.
[Question]Tricia ordered three dozen eggs. She will use 1/4 of them for making crepes, and 2/3 of the remaining for making cupcakes. How many eggs are left to make sunny-side-up eggs for breakfast?
[Answer]Since a dozen is equal to 12, then 3 dozen eggs are equal to 12 x 3 = 36 eggs. Tricia will use 36 x 1 / 4 = 9 eggs for making crepes. So there are 36 - 9 = 27 eggs left. 27 x 2 / 3 = 18 eggs will be used for making cupcakes. Thus, there are only 27 - 18 = 9 eggs left to make sunny - side - up eggs for breakfast. The answer is 9.
Q: Last year, Jorge planted corn on all of his 60 acres of property. Typically, corn grown on good soil yields 400 bushels per acre, but in clay-rich soil, the yield is only half as much per acre as in good soil. One-third of Jorge's 60 acres of land is clay-rich soil and the rest is good soil. How many bushels of corn did Jorge's land yield last year?
A: Jorge has 60 * (1 / 3) = 20 acres of clay - rich soil. He has 60 - 20 = 40 acres of good soil. At 400 bushels per acre, his 40 acres of good soil produced 40 * 400 = 16,000 bushels of corn. If good soil produces 400 bushels per acre, clay - rich soil produces 400 / 2 = 200 bushels per acre. At 200 bushels per acre, his 20 acres of clay - rich soil produced 20 * 200 = 4,000 bushels of corn. Altogether, his land produced 16,000 + 4,000 = 20,000 bushels of corn. The answer is 20000.
Question: Brenda and nine of her friends want to order a pizza. They decide that each person will eat 2 slices. If each pizza has 4 slices, how many pizzas should they order?
Answer:
All together, Brenda and her friends make a group of 1 + 9 = 10 people. If they each want to eat 2 pizza slices, there should be 10 * 2 = 20 slices. Since a pizza has 4 slices, they will have to order 20 / 4 = 5 pizzas. The answer is 5.
