Question: In 2021, Wayne is 37 years old. His brother Peter is 3 years older than him and their sister Julia is 2 years older than Peter. What year was Julia born in?
Answer: Peter is 3 years older than Wayne who is 37 so Peter is 37 + 3 = 40 years old. Julia is 2 years older than Peter who is 40 so Julia is 2 + 40 = 42 years old. It's 2021 and Julia is 42 years old so she was born in 2021 - 42 = 1979. The answer is 1979.

[Answer]In June the hobby store sold 21,122 + 3,922 = 25,044 trading cards. Over June and July the store sold 25,044 + 21,122 = 46,166 trading cards. The answer is 46166.
Q: In a Volleyball competition, Lizzie was able to score 4 points. Nathalie's score is 3 more than Lizzie's score and Aimee's score is twice the score of Lizzie and Nathalie combined. The rest of the points were made by their teammates. If the whole team was able to score 50 points, how many points did their teammates make?
A: Nathalie's score is 4 + 3 = 7. And the total points of Nathalie and Lizzie when combined is 7 + 4 = 11. So, the total score of Aimee is 11 x 2 = 22. Lizzie, Nathalie, and Aimee's total score is 22 + 11 = 33. Therefore, their teammates were able to score 50 - 33 = 17. The answer is 17.
Question: Mary bought 5 boxes of drinks at $6 each box and 10 boxes of pizzas at $14 each box for her pizza party. She paid $200 for all the items. How much change did she get back?
Answer: Mary spent 5 x $6 = $30 on drinks. She spent 10 x $14 = $140 on pizzas. She spent a total amount of $30 + $140 = $170. Therefore, Mary got a change of $200 - $170 = $30 after paying all the items for her pizza party. The answer is 30.
[Question]Cheryl is signing up for a golf tournament that costs 20% more than her monthly cell phone expenses to enter the tournament. If Cheryl spends $400 more on her monthly cell phone expenses than on the electricity bill, which costs $800, calculate the total amount she pays upon signing up for the golf tournament.
[Answer]If the electricity bill costs $800, and Cheryl spends $400 more on her monthly cell phone expenses than on the electricity bill, she pays $800 + $400 = $1200 on cell phone expenses. Since the cost to enter the tournament is 20% more than Cheryl's monthly cell phone expenses, to enter the tournament, Cheryl has to pay 20 / 100 * 1200 = $240 more than her monthly cell phone expenses. The total cost of joining the golf tournament is $1200 + $240 = $1440. The answer is 1440.
