[Question]Page collects fancy shoes and has 80 pairs in her closet. She decides to donate 30% of her collection that she no longer wears. After dropping off her donation, she treats herself and buys 6 more pairs to add to her collection. How many shoes does she have now?
[Answer]She donates 30% of her 80 pairs of shoes so that’s .30 * 80 = 24 pair of shoes she donates. She had 80 shoes in her collection and donates 24 so that leaves 80 - 24 = 56 pairs of shoes. She now has 56 pairs of shoes and buys 6 more pairs so her collection is now 56 + 6 = 62 pairs of shoes. The answer is 62.
Q: Karl sells clothing in his store. He sells a T-shirt that costs $5, some pants that cost $4, and some skirts that cost $6, he also sells some refurbished t-shirts that cost half the original price. How much is his total income if he sold two T-shirts, one pair of pants, four skirts, and six refurbished T-shirts?
A: The refurbished T - shirt costs $5 / 2 = $2.5. He earn $2.5 x 6 = $15 for the refurbished T - shirt. He can earn $5 x 2 = $10 for the T - shirts. He can earn $4 x 1 = $4 for the pants. He can earn $6 x 4 = $24 for the skirts. Therefore Karl can earn a total of $15 + $10 + $4 + $24 = $53. The answer is 53.

Q: Carly is making burgers for a neighborhood BBQ. Each burger needs to be cooked for 4 minutes on each side. Carly can fit 5 burgers on the grill at once. If half her 30 guests want 2 burgers and the other half each want 1, how long will it take Carly to cook all the burgers?
A: First find half the number of guests at Carly's party: 30 guests / 2 = 15 guests. Then multiply that number by 2 for the number of burgers half the guests want: 15 guests * 2 burgers / guest = 30 burgers. Then add the 15 burgers for the 15 guests who only want 1 to find the total number of burgers: 30 burgers + 15 burgers = 45 burgers. Then divide the total number of burgers by the number of burgers Carly can cook at once to find the number of batches she cooks: 45 burgers / 5 burgers / batch = 9 batches. Then multiply the number of sides per burger by the cooking time per side to find each burger's total cook time: 4 minutes / side * 2 sides = 8 minutes. Finally, multiply each batch's cook time by the number of batches to find the total cook time: 8 minutes / batch * 9 batches = 72 minutes. The answer is 72.
Question: Miriam currently has 30 marbles, but she used to have more. Miriam gave her brother 60 marbles, gave her sister twice that amount and gave her friend Savanna three times the amount she currently has. How many marbles did Miriam start with?
Answer:
If Mariam remains with 30 marbles after giving her brother 60 marbles, she had 30 + 60 = 90 marbles. Mariam's sister receives twice as many marbles as her brother, a total of 2 * 60 = 120 marbles. The total number of marbles before giving any to her brother or sister is 120 + 90 = 210. Savannah is to receive three times as many marbles as Mariam has to remain with, a total of 3 * 30 = 90 marbles. Before giving out any marble, Mariam has 210 + 90 = 300 marbles. The answer is 300.
