[Question]A woodworker is crafting enough furniture legs for their projects. They have made a total of 40 furniture legs so far, and this is the exact amount they needed for everything they're building. If the woodworker is using these legs for their tables and chairs and they have built 6 chairs, how many tables have they made?
[Answer]The chairs need 6 chairs * 4 legs = 24 furniture legs. This means they are using 40 legs in total 24 legs for chairs = 16 legs for the tables. They have therefore made 16 legs / 4 legs per table = 4 tables. The answer is 4.
Q: A store sells pencils and erasers. It has a rule that for every pencil you buy, you must buy 2 erasers which cost 1/2 the price of the pencils. If they sold 20 pencils and earned $80, how much do erasers cost?
A: They sold 40 erasers because 20 x 2 = 40. Therefore 20(Pencil Price) + (1 / 2)(40 x Pencil Price) = 80. Therefore 40(Pencil Price) = 80. Therefore (Pencil Price) equals 2 because 80 / 40 = 2. An eraser costs $1 because 2 / 2 = 1. The answer is 1.
Question: Jebb buys $50 worth of food at a restaurant with a service fee of 12%. After paying, he gives a $5 tip. How much money did he spend at the restaurant?
Answer: Jebb paid $50 x 12 / 100 = $6 for service fee. He paid $50 + $6 = $56 for the food and the service fee. The total cost of everything is $56 + $5 = $61. The answer is 61.
[Question]At a certain car dealership, 15% of the cars cost less than $15000 and 40% of the cars cost more than $20000. If there are 3000 cars at the dealership, how many of them cost between $15000 and $20000?
[Answer]15% of 3000 cars is (15 / 100) * 3000 = 450 cars. 40% of 3000 cars is (40 / 100) * 3000 = 1200 cars. 450 + 1200 = 1650 cars which cost either less than $15000 or more than $20000. Out of 3000 cars, there will then be 3000 - 1650 = 1350 cars left which cost between $15000 and $20000. The answer is 1350.
Q: There are 20 dolphins in the aqua park. One-fourth of the dolphins are fully trained. Two-third of the remaining dolphins are currently in training and the rest will be trained next month. How many dolphins will be trained next month?
A: 20 x 1 / 4 = 5 dolphins are fully trained. So, 20 - 5 = 15 dolphins are not yet fully trained. 15 x 2 / 3 = 10 are currently in training. Therefore, 15 - 10 = 5 dolphins will be trained next month. The answer is 5.
Question: Kenneth spent 10% of this earnings this week on a new joystick. If he is left with $405, how much were his earnings?
Answer:
Since Kenneth spent 10%, then he is left with 100% - 10% = 90% of his earnings. Since 90% of his earnings is worth $405, then 1% of his earnings is $405 / 90 = $4.50. Hence, Kenneth's earnings is $4.50 x 100 = $450. The answer is 450.
