Barbara wants to save up for a new wristwatch that costs $100. Her parents give her an allowance of $5 a week and she can either save it all up for the watch or spend it as she wishes. 10 weeks pass and due to spending some of her money on ice cream, Barbara currently only has $20. How many more weeks does she need to save for a watch if she stops spending on other things right now?

Since barbara needs $100, and she currently has $20, she is remaining with $100-$20 = $

<<100-20=80>>80 to save With an allowance of $5 each week, she'll need to save for 80/5 = 16 weeks #### 16 Jaylen has 5 carrots and 2 cucumbers. Jaylen has twice as many bell peppers as Kristin. Jaylen has 3 less than half as many green beans as Kristin. If Kristin has 2 bell peppers and 20 green beans, how many vegetables does Jaylen have in total? Jaylen has 2 * 2 = <<2*2=4>>4 bell peppers Jaylen has (20 / 2) - 3 = <<20/2-3=7>>7 green beans Jaylen has a total of 4 + 7 + 5 + 2 = <<4+7+5+2=18>>18 vegetables #### 18 Shane wants to take as many photos as possible this year. He takes 146 photos in the first 2 months of the year. In January, he takes 2 photos every day. The rest of the photos were taken in February. If in February he took an equal number of photos each week, how many photos did Shane take each week in February? Shane takes a total of 2 photos/day * 31 days = <<2*31=62>>62 photos in January. This means he must have taken 146 total photos – 62 January photos = 84 photos in February. As he took an equal number each week, he must have taken 84 photos / 4 weeks = <<84/4=21>>21 photos each week. #### 21 There is a playground that is surrounded by a square fence that has a side length of 27 yards. There is a 12 yard by 9 yard garden that has fencing around it. How many yards of fencing do the playground and garden have together? 27 * 4 = <<27*4=108>>108 yards 2 * (12 + 9) = <<2*(12+9)=42>>42 yards 108 + 42 = <<108+42=150>>150 yards The playground and garden have a combined fence length of 150 yards. #### 150 Jamestown has 20 theme parks. If Venice has 25 more theme parks than Jamestown, and Marina Del Ray has 50 more theme parks than Jamestown, calculate the number of theme parks present in the three towns. Since Venice has 25 more theme parks than Jamestown, there are 20+25 = <<20+25=45>>45 theme parks in Venice. Together, Venice and Jamestown have 45+20 = <<45+20=65>>65 theme parks With 50 more theme parks than Jamestown, Marina Del Ray has 50+20 = <<50+20=70>>70 theme parks. The total number of theme parks in the three towns is 70+65 = <<70+65=135>>135 #### 135 Steve bought $25 worth of groceries. He bought a gallon of milk for $3, two boxes of cereal for $3.5 each, 4 bananas for $.25 each, four apples that cost $.5 each and a number of boxes of cookies. The cookies cost twice as much per box as the gallon of milk. How many boxes of cookies did he get? He spent $7 on cereal because 2 x 3.5 = <<2*3.5=7>>7 He spent $1 on bananas because 4 x .25 = <<4*.25=1>>1 He spent $2 on apples because 4 x .5 = <<4*.5=2>>2 He spent 13 on everything but the cookies because 3 + 7 + 1 + 2 = 13 He spent $12 on cookies because 25 - 13 = <<25-13=12>>12 Each box of cookies is $6 because 3 x 2 = <<3*2=6>>6 He bought 2 boxes of cookies because 12 / 6 = <<12/6=2>>2 #### 2 Mike wants to buy a new phone. The cost of the phone is $1300. How much more money does Mike need if he already has 40% of the amount he needs? Mike already has 40/100 * 1300 = $<<40/100*1300=520>>520. This means he needs 1300 - 520 = $<<1300-520=780>>780 more, to buy the phone. #### 780 Giselle is in charge of the relay run on track and field day. Last year, the race was 300 meters. This year, it will be 4 times as long. Giselle needs to set up 6 tables for the relay run. The distance between the tables must be the same and the last table will be at the finish line. What is the distance between table 1 and table 3 in meters? The relay run is 4 times the length of last year’s race, so 300 meters x 4 = <<300*4=1200>>1200 meters. With 6 tables along the route, the distance between tables is 1200 meters / 6 tables = <<1200/6=200>>200 meters. The distance between tables 1 and 3 is 200 meters x 2 = <<200*2=400>>400 meters. #### 400 The fall semester lasts 15 weeks. During the weekdays, Paris studies 3 hours a day for her classes. On the weekends, she spends 4 hours studying on Saturday and 5 hours studying on Sunday. How much time does Paris study during the semester? During the weekdays, Paris studies 3 hours a day for 5*3 = <<3*5=15>>15 hours She studies 4 hours on Saturday and 5 hours on Sunday for a total of 4+5 = <<4+5=9>>9 hours on the weekends If she studies 15 hours during the weekdays and 9 hours on the weekends then she studies 15+9 = <<15+9=24>>24 hours per week There are 15 weeks in the fall semester and she studies 24 hours a week so she will spend 15*24 = <<15*24=360>>360 hours studying #### 360 Corna wants to buy a shirt. The store buys the shirt for $20, but charges 30% for profit. However, the shirt is on sale for 50% off the selling price. What is the price now? First find how much the store makes in profit: $20 * 0.30 = $<<20*0.30=6>>6 for profit Then find the regular selling price: $20 + $6 = $<<20+6=26>>26 total price Then multiply the regular price by the discount to get $26 * 0.50 = $<<26*0.50=13>>13 for the final price #### 13
