Fred has 12 identical candy bars, and Uncle Bob has 6 more. If Jacqueline has ten times the total number of candy bars Fred and Uncle Bob have, what's 40% of Jacqueline's candy bars?

If Fred has 12 identical candy bars, uncle Bob has 12+6=

<<12+6=18>>18 candy bars. Together, Fred and Uncle Bob have 12+18 = <<12+18=30>>30 candy bars. Jacqueline has ten times the total number of candy bars Fred and Uncle Bob have, meaning she has 10*30 = <<10*30=300>>300 candy bars. 40% of Jacqueline's candy bars is 40/100*300 = <<40/100*300=120>>120 #### 120 To celebrate a recent promotion, Arthur decided to treat himself to dinner at a nice restaurant. He ordered a nice appetizer for $8, a delicious ribeye steak for his entrée at $20, had two glasses of nice red wine with dinner for $3 each, and a slice of caramel cheesecake for dessert for $6. He used a voucher for half off the price of his entrée, but he very thoughtfully tipped his waitress a full 20% of what the full cost of his meal would have been without the discount. How much, including the tip, did Arthur spend on dinner? The cost of his food, before the voucher, was $8 + $20 + $3 + $3 + $6 = $<<8+20+3+3+6=40>>40. The tip was $40 * .20 = $<<40*.20=8>>8. The voucher saved him $20 / 2 = $<<20/2=10>>10. So the full price of Arthur's meal, with tip, was $40 - $10 + 8 = $<<40-10+8=38>>38. #### 38 Five years ago, the sum of Sebastian's age and his sister's age was 3/4 of their father's age. How old is their father today if Sebastian is 40 years old and 10 years older than his sister? If Sebastian is 40 years old and 10 years older than his sister, his sister is 40-10=<<40-10=30>>30 years old. Five years ago, Sebastian was 40-5=<<40-5=35>>35 years old. Similarly, Sebastian's sister's age was 30-5=<<30-5=25>>25 years old. The sum of their ages five years ago was 25+35=<<25+35=60>>60 Five years ago, the sum of Sebastian's age and his sister's age was 3/4 of their father's age, meaning their father's age was 60 / 3/4 = 80 years. The father's age is now 80+5=<<80+5=85>>85 #### 85 Kim loves to knit sweaters and can knit as many as 10 sweaters in a day if she gets the time. On a particular week, she knit 8 sweaters on Monday, 2 more sweaters on Tuesday than on Monday, 4 fewer sweaters on both Wednesday and Thursday than on Tuesday, and half the number of sweaters she had knit on Monday on Friday. Calculate the total number of sweaters she knit that week. If she knit 8 sweaters on Monday and 2 more on Tuesday, she knit 8+2 = <<8+2=10>>10 sweaters on Tuesday. The total number of sweaters she had knit on Monday and Tuesday is 10+8 = <<10+8=18>>18 On Wednesday, she knit four fewer sweaters than the number she knit on Tuesday, which totals 10-4 = <<10-4=6>>6 sweaters. By Wednesday, she had knit 18+6 = <<18+6=24>>24 sweaters. On Thursday, she knit the same number of sweaters she had knit on Thursday, giving a total of 24+6 = <<24+6=30>>30 sweaters. On Friday, she knit half the number of sweaters she had knit on Monday, which totals 1/2*8 = <<8*1/2=4>>4 sweaters on Friday. So far, she has knit 30+4 = <<30+4=34>>34 sweaters by Friday. #### 34 Tim decides to do a movie marathon. The first movie is 2 hours long. The next movie is 50% longer. And the last movie is 1 hour shorter than the combined time of the previous 2 movies. How long was his movie marathon? The second movie was 2*.5=<<2*.5=1>>1` hour longer than the first movie So the second movie was 2+1=<<2+1=3>>3 hours long That means the first two movies had a combined time of 3+2=<<3+2=5>>5 hours So the last movie had a length of 5-1=<<5-1=4>>4 hours That means the marathon lasted 5+4=<<5+4=9>>9 hours #### 9 One hundred chips were divided by Ian and Lyle in the ratio 4:6. What percentage of the chips did Lyle have? The chips were divided into 4 + 6 = <<4+6=10>>10 parts. Each part has 100/10 = <<100/10=10>>10 chips. Since Lyle owns 6 parts, then he has 6 x 10 = <<6*10=60>>60 chips. This is 60/100 x 100 = <<60/100*100=60>>60% of the entire chips. #### 60 Georgina owns a parrot and is teaching it to speak. So far, the parrot knows seventeen phrases. If she is teaching it two phrases a week and it already knew three phrases when she bought it, how many days has Georgina had it? The parrot knew 3 phrases when Georgina bought it, so it has learned 17 - 3 = <<17-3=14>>14 phrases from her. She has been teaching it 2 phrases a week, so she has had it 14 / 2 = <<14/2=7>>7 weeks. There are 7 days in a week, so Georgina has had the parrot for 7 * 7 = <<7*7=49>>49 days. #### 49 Neeley bought a loaf of bread from the store and sliced it into 12 pieces. His family ate a third of the bread slices for breakfast. Then Neeley used 2 bread slices to make a sandwich for lunch. How many slices of bread remain? For breakfast, the family ate 12 / 3 = <<12/3=4>>4 slices of bread After breakfast, the family has 12 - 4 = <<12-4=8>>8 slices of bread remaining. After Neeley's lunch, there are 8 - 2 = <<8-2=6>>6 slices of bread remaining. #### 6 Daria is raising money for a new vacuum cleaner. So far, she has collected $20 in her piggy bank and has decided to put $10 in it each week. If the vacuum cleaner costs $120, how many weeks will it take her to raise enough money to cover this expense? The vacuum cleaner costs $120, so Daria needs 120 - 20 = $<<120-20=100>>100 more. Daria will need 100 / 10 = <<100/10=10>>10 more weeks, to be able to buy the vacuum cleaner. #### 10 Yanna bought 60 apples. She gave eighteen apples to Zenny. She gave six more apples to Andrea and kept the rest. How many apples did she keep? After giving 18 apples to Zenny, Yanna remained with 60 - 18 = <<60-18=42>>42 apples. Since she also gave Andrea 6 apples, Yanna remained with 42 - 6 = <<36=36>>36 apples Therefore, Yanna kept 36 apples. #### 36
