Remi prepared a tomato nursery and planted tomato seedlings. After 20 days, the seedlings were ready to be transferred. On the first day, he planted 200 seedlings on the farm. On the second day, while working alongside his father, he planted twice the number of seedlings he planted on the first day. If the total number of seedlings transferred to the farm on these two days was 1200, how many seedlings did his father plant?

On the second day, he planted 2 * 200 seedlings =

<<2*200=400>>400 seedlings. The total number of seedlings Remi planted on the two days is 400 seedlings + 200 seedlings = <<400+200=600>>600 seedlings. If the total number of seedlings transferred from the nursery was 1200 after the second day, Remi's father planted 1200 seedlings - 600 seedlings = <<1200-600=600>>600 seedlings. #### 600 Darryl is an inventor who just designed a new machine. He had to pay $3600 for the parts to construct the machine, and $4500 for the patent he applied for once he built it. If the machine sells for $180, how many machines does Darryl need to sell to break even after the costs? Darryl paid 3600 + 4500 = $<<3600+4500=8100>>8100 in costs for the parts and patent. Thus, Darryl needs to sell 8100 / 180 = <<8100/180=45>>45 machines to break even. #### 45 Mike decides to buy a new camera. He wants to buy a top-of-the-line camera but he decides to wait for the new model to come out. The new model costs 30% more than the current model. The old camera cost $4000. He gets $200 off a $400 lens he bought. How much did he pay for the camera and lens? The new camera cost 4000*.3=$<<4000*.3=1200>>1200 more than the old camera. So the camera cost 4000+1200=$<<4000+1200=5200>>5200 The lens cost 400-200=$<<400-200=200>>200 So the total cost was 5200+200=$<<5200+200=5400>>5400 #### 5400 Carson is covering the high school football field with grass seed. Each square meter needs three times as much seed as fertilizer. If Carson uses 60 gallons of seed and fertilizer combined, how many gallons of seed does he use? Let s be the number of gallons of seed Carson uses and f be the number of gallons of fertilizer. We know that s = 3f and s + f = 60. Substituting the first equation into the second equation produces 3f + f = 60 Combining like terms, we get 4f = 60 Dividing both sides by 4, we get f = 15 Substituting that value into the equation s = 3f, we get s = 3 * 15 = <<3*15=45>>45 #### 45 Mary earns $20 washing cars and $40 walking dogs each month. If she puts half of that money away each month how long would it take her to save $150? Each month she makes 20+40=$<<20+40=60>>60 Every month she saves 60/2=$<<60/2=30>>30 To save $150 it will take her 150/30=<<150/30=5>>5 months #### 5 Colt and Curt prepared 113 meals to be given away to a charity. Unexpectedly, Sole Mart provided 50 more meals. If Colt and Curt have given 85 meals already, how many more meals are left to be distributed? There are 113 + 50 = <<113+50=163>>163 meals in total. After Colt and Curt gave away 85 meals, there are 163 - 85 = <<163-85=78>>78 more meals left to be distributed. #### 78 Ernest bought 50 meters of wire and cut it into 5 equal parts. He then used 3 parts of the wire. How many meters of wire is not used? Each part of the wire is 50/5 = <<50/5=10>>10 meters long. Ernest used 3 parts, then he used 10 x 3 = <<3*10=30>>30 meters of the wire. Therefore, 50 - 30 = <<50-30=20>>20 meters of wire is not used. #### 20 There were 140 kids in the junior prom. Of those, a fourth of them were dancers. Of the dancers, 25 danced the slow dance. How many of the dancer students did not slow dance? 140/4 = <<140/4=35>>35 of the students were dancers. 35-25 = <<35-25=10>>10 of the dancer students did not slow dance. #### 10 A group of bedbugs infested an old mattress. Every day, the number of bedbugs would triple. After four days, there were 810 bedbugs burrowing into the mattress. How many bedbugs did the group start with? On the third day, there were one-third of the number of bedbugs as the fourth day, so there were 810 / 3 = <<810/3=270>>270 bedbugs. On the second day, there were one-third of the third day’s bedbugs, so there were 270 / 3 = <<270/3=90>>90 bedbugs. On the first day, there were 90 / 3 = <<90/3=30>>30 bedbugs in the group to start with. #### 30 Danny is bringing his sailboat out to the ocean. When he uses his 24 square foot sail he goes 50 MPH. When he uses his 12 square foot sail he goes 20 MPH. He plans to travel 200 miles. How many hours faster is the bigger sail than the smaller one? The bigger sail will make the trip in 4 hours because 200 / 50 = <<200/50=4>>4 The smaller sail will make the trip in 10 hours because 200 / 20 = <<200/20=10>>10 The bigger sail will be 6 hours faster because 10 - 4 = <<10-4=6>>6 #### 6
