Question: Gemma ordered four pizzas at $10 each, and she gave a $5 tip to the delivery person. How much change did she get back if she gives one fifty-dollar bill?
Answer: The cost of the four pizzas is 4 x $10 = $40. The total cost, including the tip, is $40 + $5 = $45. Therefore, Gemma gets a change of $50 - $45 = $5. The answer is 5.
[Question]Jason is tired of the neighborhood animals raiding his trash. He pepper-sprays some raccoons and 6 times as many squirrels. If he pepper-sprays 84 animals total, how many raccoons does he pepper-spray?
[Answer]Let r be the number of raccoons Jason pepper - sprays and s be the number of squirrels. We know that r + s = 84 and s = 6r. Substituting the second equation into the first equation, we get r + 6r = 84. Combining like terms, we get 7r = 84. Dividing both sides by 7, we get r = 12. The answer is 12.
Q: Yvonne swims 10 laps in 5 minutes. Her younger sister can swim half as many laps as Yvonne in the same time frame. Their brother Joel can swim three times the number of laps as the youngest sister. How many laps can Joel swim?
A: Yvonne swims 10 laps in 5 minutes and her younger sister swims half as many laps in 5 minutes so she swims 10 / 2 = 5 laps in 5 minutes. Joel can swim 3 times the amount of his youngest sister’s 5 laps so he can swim 3 * 5 = 15 laps in 5 minutes. The answer is 15.
Question: On Rudolph's car trip across town, he traveled 2 more than 5 miles and encountered 3 less than 17 stop signs. How many stop signs per mile did Rudolph encounter on his trip across town?
Answer: He traveled 2 more than 5 miles, or 5 + 2 = 7 miles. He encountered 3 less than 17 stop signs, or 17 - 3 = 14 stop signs. Thus, during his trip across town, Rudolph encountered 14 / 7 = 2 stop signs per mile. The answer is 2.
[Question]A company has 1000 employees. There will be three rounds of layoffs. For each round of layoff, 10% of the remaining employees will be laid off. How many employees will be laid off in total?
[Answer]The first round will result in 1000 * 10% = 100 employee layoffs. There are 1000 - 100 = 900 employees remaining. The second round will result in 900 * 10% = 90 employee layoffs. There are 900 - 90 = 810 employees remaining. The third round will result in 810 * 10% = 81 employee layoffs. The total number of of employees laid off is 100 + 90 + 81 = 271. The answer is 271.
