John is budgeting for his marriage. The venue cost $10,000. It cost $500 for each guest, and John wants 50 guests while his wife wants 60% more than that. How much would the wedding cost if John's wife gets her way? Give the rationale and then the answer.
Let's think step by step. The bride wanted 50 * .6 = 30 more guests than the husband. So the bride wanted 50 + 30 = 80 guests. So the guests cost 80 * $500 = $40000. So the total cost was $40000 + $10,000 = $50000.. The answer is: 50000.

There are 235 books in a library. On Tuesday, 227 books are taken out. On Thursday, 56 books are brought back and 35 books are taken out again on Friday. How many books are there now? Give the rationale and then the answer.
Let's think step by step. On Tuesday, 227 books were taken, so there are 235 - 227 = 8 books left. 56 books were brought back on Thursday, so there are 8 + 56 = 64 books in the library. Finally, 35 books are taken out on Friday, leaving 64 - 35 = 29 books available.. The answer is: 29.

Ryan has 40 balls. There are twice as many red balls as blue while the rest are green. If there are 11 blue balls, how many green balls are there? Give the rationale and then the answer.
Let's think step by step. There are 11 blue x 2 red / blue = 22 red balls. The total number of blue and red balls is 11 blue + 22 red = 33 balls. There are 40 balls - 33 balls = 7 green balls.. The answer is: 7.
