[Answer]She spent 4 x $1.5 = $6 for the four bell peppers. She spent 2 x $3 = $6 for the 2 pounds of meat. So, Pauline spent $5 + $6 + $6 = $17 in all. The answer is 17.
Q: Rachel and Sara want to attend a beauty and modeling contest. They both want to buy new pairs of shoes and dresses. Sara buys a pair of shoes which costs $50 and a dress which costs $200. How much should Rachel budget if she wants to spend twice as much as what Sara spent on the pair of shoes and dress?
A: The cost Rachel should budget for her pair of shoes is $50 * 2 = $100. The cost Rachel should budget for her dress is $200 * 2 = $400. The total Rachel should budget is $100 + $400 = $500. The answer is 500.
Question: Valerie needs to put stamps on the envelopes she is about to mail. She has thank you cards for each of her grandmother, uncle and aunt for the birthday presents they sent. She also has to pay the water bill and the electric bill separately. She wants to send three more mail-in rebates than she does bills and she has twice as many job applications as rebates to mail. How many stamps does she need if everything needs 1 stamp except the electric bill, which needs 2?
Answer: Valerie has to send a thank you card to each of 3 people, so she has 3 * 1 = 3 thank you cards to mail. She has 2 bills to mail. She has 3 more rebates than bills, so 3 + 2 = 5 mail - in rebates to mail. She has twice as many job applications as rebates, so she has 2 * 5 = 10 applications to mail. She has 3 + 2 + 5 + 10 = 20 pieces of mail to send. The electric bill needs an extra stamp, so she needs 20 + 1 = 21 stamps. The answer is 21.
[Question]Cupcakes are sold in packages of 10 and 15. Jean bought 4 packs of 15 cupcakes. If she will give one cupcake each to 100 children in the orphanage, how many packs of 10 cupcakes should she need to buy?
[Answer]Jean already bought 15 cupcakes x 4 packs = 60 cupcakes. She needs 100 - 60 = 40 more cupcakes. Thus, she needs to buy 40 / 10 = 4 packs of 10 cupcakes. The answer is 4.
[Question]In a conference room, 40 chairs with a capacity of 2 people each were arranged in rows in preparation for the board meeting of a company, whose number of members was the same as the chairs' capacity. If 2/5 of the chairs were not occupied, and the rest each had two people, calculate the number of board members who did attend the meeting.
[Answer]
The total capacity of the 40 chairs was 40 * 2 = 80 people. If 2 / 5 of the chairs were unoccupied, 2 / 5 * 80 = 32 people missed the board meeting since the number of members was the same as the chair's capacity. The number of board members who attended the meeting was 80 - 32 = 48. The answer is 48.
