Tim is 5 years old. His cousin, Rommel, is thrice as old as he is. His other cousin, Jenny, is 2 years older than Rommel. How many years younger is Tim than Jenny?

Rommel is 5 x 3 =

<<5*3=15>>15 years old. Jenny is 15 + 2 = <<15+2=17>>17 years old. So, Tim is 17 - 5 = <<17-5=12>>12 years younger than Jenny. #### 12 On a three-day trip, Wendy drove 125 miles on the first day, and 223 miles on the second day. How many miles did she drive on the third day, if the total miles that Wendy drove for the trip is 493 miles? Wendy drove 125 miles + 223 miles = <<125+223=348>>348 miles on the first two days. So on the third day, she drove 493 miles - 348 miles = <<493-348=145>>145 miles. #### 145 Andy needs to drive from Salt Lake City to Los Angeles. The drive from Salt Lake City to Las Vegas is 420 miles. The drive from Las Vegas to Los Angeles is 273 miles. He wants to make the drive in 11 hours. What's the average minimum speed that Andy needs to drive to reach Los Angeles in 11 hours? The total distance of the trip is 420 + 273 = <<420+273=693>>693 miles. To make the trip Andy must drive 693 miles / 11 hours = <<693/11=63>>63 miles per hour. #### 63 Mark started the day with 14 buttons. His friend Shane gave him 3 times that amount of buttons. Then his other friend Sam asked if he could have half of Mark’s buttons. How many buttons did Mark end up with? Shane gave Mark 14*3=<<14*3=42>>42 buttons After that Mark had 42+14=<<42+14=56>>56 buttons Then Mark gave 56/2=<<56/2=28>>28 buttons to Shane Which left Mark with 28 buttons #### 28 Tom decides to make lasagna with all his beef. It takes twice as many noodles as beef. He has 10 pounds of beef. He already has 4 pounds of lasagna noodles and the noodles come in 2-pound packages. How many packages does he need to buy? He needs 10*2=<<10*2=20>>20 pounds of noodles That means he needs to buy 20-4=<<20-4=16>>16 pounds of noodles So he needs to buy 16/2=<<16/2=8>>8 packages #### 8 For the funfair, the school organizers ordered 30 rolls of tickets. Each roll of tickets has 100 tickets. The 4th graders bought 30% of the tickets while the 5th graders bought 50% of the remaining tickets. Then the 6th graders bought a total of 100 tickets. How many tickets were left unsold? There were a total of 30 x 100 = <<30*100=3000>>3000 tickets ordered by the school organizers. The 4th graders bought 3000 x 30/100 = <<3000*30/100=900>>900 tickets. So, there were 3000 - 900 = <<3000-900=2100>>2100 tickets left for the other two grade levels. The 5th graders bought 2100 x 50/100 = <<2100*50/100=1050>>1050 tickets. So, 2100 - 1050 = <<2100-1050=1050>>1050 tickets were left then. Since 100 tickets were bought by the 6th graders, therefore 1050 - 100 = <<950=950>>950 tickets were left unsold. #### 950 Kekai is running a sundae booth at the carnival. On Monday, he makes a total of 40 sundaes, and he puts 6 m&ms on each sundae. On Tuesday, he makes a total of 20 sundaes, and he puts 10 m&ms on each sundae. If each m&m pack contains 40 m&ms, how many m&m packs does Kekai use? On Monday, Kekai uses 40 * 6 = <<40*6=240>>240 m&ms On Tuesday, Kekai uses 20 * 10 = <<20*10=200>>200 m&ms Kekai uses a total of 240 + 200 = <<240+200=440>>440 m&ms Kekai uses a 440 / 40 = <<440/40=11>>11 m&m packs #### 11 A play was held in an auditorium and its ticket costs $10. An auditorium has 20 rows and each row has 10 seats. If only 3/4 of the seats were sold, how much was earned from the play? There are 20 x 10 = <<20*10=200>>200 seats in the auditorium. Only 200 x 3/4 = <<200*3/4=150>>150 seats were sold. Hence, the earnings from the play is $10 x 150 = $<<10*150=1500>>1500. #### 1500 50% of substitute teachers walk out after 1 hour of teaching. 30% of the remainder quit before lunch. If 60 substitute teachers show up at 7 AM, how many will be left after lunch? First find the number of substitute teachers left after half quit: 60 teachers / 2 = <<60/2=30>>30 teachers Then find how many teachers quit after an hour but before lunch: 30 teachers * 30% = <<30*30*.01=9>>9 teachers Then subtract that number from the number of teachers left after one hour to find how many are left after lunch: 30 teachers - 9 teachers = <<30-9=21>>21 teachers #### 21 Andy and Dawn spent the weekend cleaning the house. When putting away the laundry Andy took six minutes more than two times the number of minutes it took Dawn to wash the dishes. If it took Dawn 20 minutes to wash the dishes how many minutes did it take Andy to put away the laundry? Two times the minutes it took Dawn to wash the dishes is 20*2= <<20*2=40>>40 Andy took 40+6= <<40+6=46>>46 minutes to put away the laundry #### 46
