Answer this question:Lily goes to the supermarket. She has $60. She needs to buy 6 items: celery, cereal, bread, milk, potatoes, and coffee. She finds a stalk of celery for $5, cereal for 50% off $12, bread for $8, and milk for 10% off $10. She finds potatoes for $1 each and buys 6. How many dollars does she have left to spend on coffee?
Lily spends $5 + $8 = $13 on celery and bread. Lily spends $12 * (50 / 100) = $6 on cereal. Lily gets 10% off the milk, so she pays 100% - 10% = 90% of its original price. Lily spends $10 * 90% = $9 on milk. She spends $1 * 6 = $6 on potatoes. Thus, she has $60 - $13 - $6 - $9 - $6 = $26 left over for coffee.
The answer is 26.

Answer this question:A boy has 12 oranges. He gives one-third of this number to his brother, one-fourth of the remainder to his friend and keeps the rest for himself. How many does his friend get?
He gives a third of 12 oranges to his brother which is 12 * (1 / 3) = 4 oranges. He has 12 - 4 = 8 oranges left. He gives a fourth of 8 oranges to his friend which is 8 * (1 / 4) = 2 oranges.
The answer is 2.

Answer this question:In his first season at Best Hockey's team, Louie scored four goals in the last hockey match of this season. His brother has scored twice as many goals as Louie scored in the last match in each game he's played in each of the three seasons he's been on the team. Each season has 50 games. What is the total number of goals the brothers have scored between them if, in the previous matches, Louie scored 40 goals?
If Louie scored 4 goals last night, his brother has scored 2 * 4 goals = 8 goals in each game. The total number of games Louie's brother has played in is 3 seasons * 50 games / season = 150 games. Louie's brother's total number of goals in the three seasons is 8 goals / game * 150 games = 1200 goals. Louie's total number of goals this season is 40 goals + 4 goals = 44 goals. Together, they have a total of 44 goals + 1200 goals = 1244 goals in the team.
The answer is 1244.

Answer this question: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?
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.
