Question: A pole is 20 meters long. It got cut in a way that left it 30% shorter. How long is the pole?
Answer: The cut - away part of the pole is 30 / 100 * 20 = 6 meters long. So the pole is left at the length of 20 - 6 = 14 meters. The answer is 14.
[Question]Martha collected 90 cans while Diego collected 10 more than half the cans collected by Martha. If both of them should collect a total of 150 cans for their project, how many more cans do they need to collect?
[Answer]Half the cans collected by Martha is 90 / 2 = 45. So, Diego collected 45 + 10 = 55 cans. Martha and Diego collected 90 + 55 = 145 cans together. Thus, they need to collect 150 - 145 = 5 more cans. The answer is 5.
Q: The sum of Mario and Maria's ages now is 7. Mario is 1 year older than Maria. How old is Mario?
A: If x is Maria's age, then Mario's age is x + 1. The equation that represents the sum of their ages is x + x + 1 = 7. By combining like terms, the equation becomes 2x = 6. Hence, the value of x which represents the age of Maria is 6 / 2 = 3. So Mariu is 3 + 1 = 4 years old. The answer is 4.
Question: Crystal wanted to sell everything left in her pastry class before closing for the night. She reduced her $3.00 cupcakes and her $2.00 cookies by half. How much money did she make if she sold the last 16 cupcakes and 8 cookies?
Answer: She reduced the price of the $3.00 cupcakes by half so they are now 3 / 2 = $1.50. She reduced the price of the $2.00 cookies by half so they are now 2 / 2 = $1.00. She sold 16 cupcakes at $1.50 each so she made = 16 * 1.50 = $24.00. She sold 8 cookies at $1.00 each so she made 8 * 1 = $8.00. She made $24.00 from the cupcakes and $8.00 from the cookies for a total of 24 + 8 = $32.00. The answer is 32.
[Question]Reese had a sum of money in her savings account. The company she used to work with was not doing well which is why she lost her job. So she spent 20% of her savings for her expenses in February, 40% of it in March, and $1500 in April. How much did she have in her savings account if she still has $2900 after spending those amounts?
[Answer]The total percentage of money that Reese spent in February and March is 20% + 40% = 60%. This means the April expenses and the money left in her account make up 100% - 60% = 40% of her savings. Reese had $2900 + $1500 = $4400 for the April expenses and the money left in her account. So, $4400 is equal to 40% which means every 1% is equal to $4400 / 40 = $110. Therefore, Reese originally had $110 x 100 = $11000 in her savings account. The answer is 11000.
