[Question]Kristy baked cookies because her friends are coming over to her house. She ate 2 of them and gave her brother 1 cookie. Her first friend arrived and took 3 cookies. The second and third friends to arrive took 5 cookies each. If there are 6 cookies left, how many cookies did Kristy bake?
[Answer]There were 6 + 5 = 11 cookies left before the third friend took 5. There were 11 + 5 = 16 cookies left before the second friend took 5. There were 16 + 3 = 19 cookies left before the first friend took 3. There were 19 + 1 = 20 cookies left before Kristy gave 1 cookie to her brother. There were 20 + 2 = 22 cookies that Kristy baked. The answer is 22.

Question: Bella eats 6 apples a day. If during the week she consumes a third of the apples Grace picks, how many apples will Grace have after 6 weeks?
Answer: Bella eats during the week, 6 apples / day * 7 days / week = 42 apples / week. Grace harvests 42 apples / week * 3 = 126 apples during the week. Leftover after Bella eats, 126 apples / week - 42 apples / week = 84 apples / week. After 6 weeks Grace will have 84 apples / week * 6 weeks = 504 apples. The answer is 504.

Q: Toby wants to walk an average of 9,000 steps per day over the next week. On Sunday he walked 9,400 steps. On Monday he walked 9,100 steps. On Tuesday he walked 8,300 steps. On Wednesday he walked 9,200 steps. On Thursday he walked 8,900 steps. How many steps does he need to average on Friday and Saturday to meet his goal?
A: He needs to walk 63,000 steps in a week because 7 x 9,000 = 63,000. He has 18,100 steps to walk on Friday and Saturday because 63,000 - 9,400 - 9,100 - 8,300 - 9,200 - 8,900 = 18,100. He needs to walk an average of 9,050 on Friday and Saturday because 18,100 / 2 = 9,050. The answer is 9050.
