A: Jed is 25 - 10 = 15 years old now. So, Matt is 15 - 10 = 5 years old now. Thus, the sum of their present ages is 15 + 5 = 20. The answer is 20.
Question: Stacy just bought a 6 month prescription of flea & tick medicine for her dog for $150.00 online. Her cashback app was offering 10% cashback and she has a mail-in rebate for $25.00 on a 6-month prescription. How much will the medicine cost after cash back and rebate offers?
Answer: Her cash back app gave her 10% back on $150.00 so that's .10 * 150 = $15.00 cash back. She received $15.00 from the cashback app and has a $25.00 mail - in rebate for a total of 15 + 25 = $40.00 discounts. She spent $150.00 for the medicine and has $40.00 worth of discounts so the medicine will cost 150 - 40 = $110.00. The answer is 110.
[Question]Prejean's speed in a race was three-quarters that of Rickey. If they both took a total of 70 minutes to run the race, calculate the total number of minutes that Rickey took to finish the race.
[Answer]Let's say Rickey took t minutes to finish the race. If Prejean's speed in the race was three - quarters that of Rickey, and Rickey took t minutes to finish the race, the time that Prejean took to finish the race is 3 / 4 * t = 3 / 4t. Together, Rickey and Prejean took t + 3 / 4t = 70. They took 1 3 / 4 t hours = 70 to finish the race. This is 7 / 4t = 70. t = 70 * 4 / 7. The time that Rickey took to finish the race is t = 40 minutes. The answer is 40.
Q: Mr. Roberts can buy a television for $400 cash or $120 down payment and $30 a month for 12 months. How much can he save by paying cash?
A: Mr. Roberts will make a total payment of $30 x 12 = $360 for 12 months. Thus, the television costs $360 + $120 = $480 when not paid in cash. Therefore, Mr. Roberts can save $480 - $400 = $80 by paying cash. The answer is 80.
