During the Mardi Gras parade, Latch caught four less than three times as many necklaces as did Rhonda. If Rhonda caught half as many necklaces as did Boudreaux, and Boudreaux caught twelve necklaces, how many necklaces did Latch catch?

Rhonda caught half as many necklaces as did Boudreaux, or 12/2=

<<12/2=6>>6 necklaces. Three times as many necklaces as Rhonda caught is 6*3=<<6*3=18>>18 necklaces. Thus, Latch caught four less than three times as many necklaces as did Rhonda, for a total of 18-4=14 necklaces. #### 14 Cora started reading a 158-page book on Monday, and she decided she wanted to finish it by the end of Friday. She read 23 pages on Monday, 38 pages on Tuesday, and 61 pages on Wednesday. She knows she will have time to read twice as much on Friday as she does on Thursday. How many pages does she have to read on Thursday to finish the book in time? Let P be the number of pages Cora has to read on Thursday. If she finishes the book by the end of Friday, she will have read 23 + 38 + 61 + P + 2P = 158 pages. The pages she has left to read by Thursday are P + 2P = 3P = 158 - 23 - 38 - 61 = pages. Thus, by Thursday she has 3P = 36 pages left to read. Therefore, to finish the book on Friday, Cora has to read P = 36 / 3 = <<36/3=12>>12 pages on Thursday. #### 12 At the family reunion, everyone ate too much food and gained weight. Orlando gained 5 pounds. Jose gained two pounds more than twice what Orlando gained. Fernando gained 3 pounds less than half of what Jose gained. How much weight, in pounds, did the three family members gain at their reunion? Twice what Orlando gained is 2*5=<<2*5=10>>10 pounds. Jose gained two pounds more than twice what Orlando gained for a total of 2+10=<<2+10=12>>12 pounds.. Half of what Jose gained is 12/2=<<12/2=6>>6 pounds. Fernando gained 3 pounds less than half of what Jose gained, for a total of 6-3=<<6-3=3>>3 pounds. In total, the three family members gained 5+12+3=<<5+12+3=20>>20 pounds at the reunion. #### 20 Denise will be 25 years old in two years. Her sister, Diane, is 4 years younger. In how many years will Diane be 25 years old? Denise is 25 - 2 = <<25-2=23>>23 years old now. So, Diane is 23 - 4 = <<23-4=19>>19 years old now. Diane will be 25 years old in 25 - 19 = <<25-19=6>>6 years. #### 6 Tina's classroom has the same amount of students as Maura's. Zack's classroom has half the amount of total students between Tina and Maura's classrooms. How many students are there in total between the 3 classrooms if when Zack was sick there were 22 students in his class? If Zack's classroom had 22 students when he was absent, then the total students in his class are 22+1 = <<22+1=23>>23 If Tina's classroom has as many students as Maura's then T=M If Zack's classroom has half the amount of total students between Tina and Maura's classrooms then 23 = 1/2* (T+M ) 23 = 1/2*(T+M) We know from above that T=M, therefore 23 = (1/2) * (M+M) or 23 = (1/2)*2M 23 = M Because T = M, then T is also T=23. Between the three classes then we have a total of T+M+Z or 23+23+23=<<23+23+23=69>>69 #### 69 John takes a pill every 6 hours. How many pills does he take a week? He takes 24/6=<<24/6=4>>4 pills a day So he takes 4*7=<<4*7=28>>28 pills a week #### 28 Leila and her friends want to rent a car for their one-day trip that is 150 kilometers long each way. The first option for a car rental costs $50 a day, excluding gasoline. The second option costs $90 a day including gasoline. A liter of gasoline can cover 15 kilometers and costs $0.90 per liter. Their car rental will need to carry them to and from their destination. How much will they save if they will choose the first option rather than the second one? Leila and her friends will travel a total distance of 150 x 2 = <<150*2=300>>300 kilometers back-and-forth. They will need 300/15 = <<300/15=20>>20 liters of gasoline for this trip. So, they will pay $0.90 x 20 = $<<0.90*20=18>>18 for the gasoline. Thus, the first option will costs them $50 + $18 = $<<50+18=68>>68. Therefore, they can save $90 - $68 = $<<90-68=22>>22 if they choose the first option. #### 22 Kendra tracks the different species of birds they spot on their birdwatching trip. On Monday they visited 5 sites and saw an average of 7 birds at each site. On Tuesday, Kendra visited 5 sites and saw an average of 5 birds at each site. On Wednesday visited 10 sites and saw an average of 8 birds at each site. On average, how many different birds did Kendra see on each site? On Monday Kendra saw 5 sites x 7 birds/site = <<5*7=35>>35 different birds On Tuesday Kendra saw 5 sites x 5 birds/site = <<5*5=25>>25 different birds On Wednesday Kendra saw 10 sites x 8 birds/site = <<10*8=80>>80 different birds In total Kendra saw 35 birds + 25 birds + 80 birds = <<35+25+80=140>>140 different birds In total Kendra visited 5 sites + 5 sites + 10 sites = <<5+5+10=20>>20 sites. On average Kendra saw 140 birds / 20 sites = <<140/20=7>>7 different birds at each site #### 7 Tony lifts weights as a form of exercise. He can lift 90 pounds with one arm in the exercise known as "the curl." In an exercise known as "the military press," he can lift over his head twice the weight that he can curl. His favorite exercise is known as "the squat" and he can squat 5 times the weight that he can lift in the military press. How much weight, in pounds, can Tony lift in the squat exercise? If Tony can curl 90 pounds, he can military press 2*90=<<90*2=180>>180 pounds. Therefore, Tony can squat 5*180=<<5*180=900>>900 pounds. #### 900 Lola baked 13 mini cupcakes, 10 pop tarts, and 8 blueberry pies. Meanwhile, Lulu made 16 mini cupcakes, 12 pop tarts, and 14 blueberry pies. How many pastries have Lola and Lulu made altogether? They made 13 + 16 = <<13+16=29>>29 mini cupcakes altogether. They made 10 + 12 = <<10+12=22>>22 pop tarts altogether. They also made 8 + 14 = <<8+14=22>>22 blueberry pies altogether. Therefore they made a total of 29 + 22 + 22 = <<29+22+22=73>>73 pastries altogether. #### 73
