Q: Matilda had 20 chocolate bars and shared them evenly amongst herself and her 4 sisters. When her father got home from work, he was upset that they did not put aside any chocolates for him. They felt bad, so they each gave up half of their chocolate bars for their father. Their father then gave 3 chocolate bars to their mother and ate 2. How many chocolate bars did Matilda's father have left?
A: Matilda and her sisters each got 20 chocolate bars / 5 people = 4 chocolate bars / person. They each gave 4 / person / 2 = 2 chocolate bars / person to their father. Their father received 2 chocolate bars / person x 5 people = 10 chocolate bars. Their father had 10 chocolate bars - 3 chocolate bars - 2 chocolate bars = 5 chocolate bars left. The answer is 5.
Question: Cristian has 50 more black cookies in his cookie jar than white cookies. He eats half of the black cookies and 3/4 of the white cookies. If he initially had 80 white cookies, how many cookies are remaining within the cookie jar altogether?
Answer: Cristian eats 3 / 4 * 80 = 60 white cookies from the jar, 3 / 4 of the total number of white cookies in the cookie jar. The number of white cookies remaining in the cookie jar is 80 - 60 = 20. In his cookie jar, Cristian also has 80 + 50 = 130 black cookies. He eats 1 / 2 * 130 = 65 black cookies from the cookie jar. He remains with 130 - 65 = 65 black cookies after eating half of them. In total, Cristian has 65 + 20 = 85 cookies remaining in the jar. The answer is 85.

Q: Salaria is growing oranges this summer. She bought two types of trees. She has 50% of tree A and 50% of tree B. Tree A gives her 10 oranges a month and 60% are good. Tree B gives her 15 oranges and 1/3 are good. If she gets 55 good oranges per month, how many total trees does she have?
A: Each tree A gives her six good oranges a month 10 x .6 = 6. Each tree B gives her five good oranges a month because 15 x (1 / 3) = 5. On average, a tree gives her 5.5 oranges a month because .5(6) + .5(5) = 5.5. She has ten total trees because 55 / 5.5 = 10. The answer is 10.
Question: During the soccer match, The Kickers scored 2 goals in the first period and twice that amount in the second period. The other team, The Spiders, scored half the amount that The Kickers scored in the first period and twice the amount that The Kickers scored in their second period. What is the total amount of goals both teams scored?
Answer: The Kickers scored twice as many as 2 goals in the second period, so 2 * 2 = 4 goals. The Spiders scored half as many as The Kickers' 2 goals from the 1st period so .5 * 2 = 1 goal in the first period. The Spiders scored twice as many as The Kickers' 4 goals from the second period, so 2 * 4 = 8 goals in the second period. Together, they scored 2 + 4 + 1 + 8 = 15 goals total. The answer is 15.
