Question: Angeli had 90 assorted candies. One-third of the candies were lollipops and the rest were candy canes. She then shared the lollipops equally among the boys such that each boy received 3. She then shared the candy canes equally among the girls such that each received 2. How many boys and girls were given altogether?
Answer: There were 90 / 3 = 30 lollipops. So, 90 - 30 = 60 are candy canes. Each boy received 3 lollipops, so there were 30 / 3 = 10 boys. Each girl received 2 candy canes, so there were 60 / 2 = 30 girls. Altogether, there were 10 + 30 = 40 boys and girls. The answer is 40.
[Question]An auto shop buys tires to replace all the tires on every customer’s car. They buy the tires as soon as cars are brought into the shop. There are four cars in the shop already, and another six customers come into the shop throughout the week. Some of the customers decide they don't want any of the tires changing, and two customers decide they only want half the tires changing. They had no tires in stock at the start of the week. If the shop has 20 tires left at the end of the week, how many customers decided they did not want their tires changing?
[Answer]A total of 4 + 6 = 10 cars are in the shop throughout the week. This means the shop buys 10 cars * 4 tires = 40 tires. For each of the customers that only want half the tires changing, there are 4 tires * 0.5 = 2 tires left over. Two of the customers only want half the tires changing, so there are 2 tires * 2 cars = 4 tires left over from these customers. Out of the remaining tires, there are 20 – 4 = 16 tires left from customers who don't want their tires changing. So in total, there were 16 tires / 4 tires per customer = 4 customers who did not want their tires changing. The answer is 4.
Q: Kristy baked cookies because her friends are coming over to her house. She ate 2 of them and gave her brother 1 cookie. Her first friend arrived and took 3 cookies. The second and third friends to arrive took 5 cookies each. If there are 6 cookies left, how many cookies did Kristy bake?
A: There were 6 + 5 = 11 cookies left before the third friend took 5. There were 11 + 5 = 16 cookies left before the second friend took 5. There were 16 + 3 = 19 cookies left before the first friend took 3. There were 19 + 1 = 20 cookies left before Kristy gave 1 cookie to her brother. There were 20 + 2 = 22 cookies that Kristy baked. The answer is 22.
Question: A box of six popsicles was left out in the sun and is slowly melting. Every time a popsicle melts the remaining popsicles melt twice as fast as the previous one. How many times faster than the first popsicle does the last popsicle’s remains melt?
Answer: The remains of the second popsicle melt 2 * 1 = 2 times as fast as the first. The remains of the third popsicle melt 2 * 2 = 4 times as fast as the first. The remains of the fourth popsicle melt 2 * 4 = 8 times as fast as the first. The remains of the fifth popsicle melt 2 * 8 = 16 times as fast as the first. The remains of the sixth popsicle melt 2 * 16 = 32 times as fast as the first popsicle. The answer is 32.
Q: Leila spent $40 which is 1/4 of her money on a sweater. She was then left with $20 after spending the rest of her money on buying pieces of jewelry. How much more did Leila spend on jewelry than on the sweater?
A:
Since 1 / 4 of her money is $40, then Leila originally had $40 x 4 = $160. $160 - $40 = $120 was left after buying a sweater. Since she is left with $20, Leila spent $120 - $20 = $100 on jewelry. Therefore, she spent $100 - $40 = $60 more for jewelry than on a sweater. The answer is 60.
