Sarah is planning to do some baking. She buys 5 pounds of rye flour, 10 pounds of whole-wheat bread flour, and 3 pounds of chickpea flour. Sarah already had 2 pounds of whole-wheat pastry flour at home. How many pounds of flour does she now have?

She bought 5+10+3=

<<5+10+3=18>>18 pounds She now has 18+2=<<18+2=20>>20 pounds #### 20 Luke started working on a 1000-piece jigsaw puzzle. The first day he worked on it, he put together 10% of the pieces. On the second day, he put together another 20% of the remaining pieces from the first day. On the third day, he put together 30% of the remaining pieces from the previous day. How many pieces does he have left to complete after the third day? Luke started putting together, 1000 x 0.1 = <<1000*0.1=100>>100 pieces. The next day, there were 1000-100 = <<1000-100=900>>900 pieces left. Then he put together 900 * 0.2 = <<900*0.2=180>>180 pieces on the second day. So there were 900 - 180 = <<900-180=720>>720 pieces left. On the third day, he put together 720 * 0.3 = <<720*0.3=216>>216 pieces. Therefore, Luke still has 720 - 216 = <<720-216=504>>504 pieces left to complete the puzzle. #### 504 Tiffany attends the carnival and her mother gives her $3 to play on a ring toss game. For every red bucket she tosses a ring into she gets 2 points. For every green bucket she gets three points. She gets zero points for a miss. Every play costs her $1 and she gets 5 rings per play. She's played two games and already gotten 4 red buckets and 5 green buckets. If she plays until her money runs out, what is the most total points she can get for all three games? She has 8 points from red buckets because 4 x 2 = <<4*2=8>>8 She has 15 points from green buckets because 5 x 3 = <<5*3=15>>15 She has spent $2 on games because 2 x 1 = <<2*1=2>>2 She has $1 left to spend because 3 - 2 = <<3-2=1>>1 She can play one more game because 1 / 1 = <<1/1=1>>1 The best bucket gives three points because 3 > 2 The most she can earn in the final game is 15 because 5 x 3 = <<5*3=15>>15 The most she can score overall is 38 because 8 + 15 + 15 = <<8+15+15=38>>38 #### 38 Tom paints a room that has 5 walls. Each wall is 2 meters by 3 meters. John can paint 1 square meter every 10 minutes. He has 10 hours to paint everything. How many hours does he have to spare? Each wall is 2*3=<<2*3=6>>6 square meters So each wall takes 6*10=<<6*10=60>>60 minutes to paint So it takes 60/60=<<60/60=1>>1 hour to paint each wall That means in total it takes 5*1=<<5*1=5>>5 hours to paint So he has 10-5=<<10-5=5>>5 hour left after finishing painting #### 5 Anna wears a size 2. Her friend Becky wears a size three times larger than Anna's. Ginger wears a size twice Becky's size minus 4. What size does Ginger wear? First find what size Becky wears: 2 * 3 = <<2*3=6>>6 Then multiply that number by 2: 6 * 2 = <<6*2=12>>12 Then subtract 4 to find Ginger's size: 12 - 4 = <<8=8>>8 #### 8 Bill thought he bought 70 chihuahuas, but some of them turned out to be rats. If the number of rats was 6 times the number of chihuahuas, how many rats did he buy? Let r be the number of rats and c be the number of real chihuahuas. We know that r + c = 70 and r = 6c. Substituting the second equation into the first equation, we get 6c + c = 70. Combining like terms, we get 7c = 70 Dividing both sides by 7, we get c = 10 Substituting this back into r = 6c, we get r = 10 * 6 = <<6*10=60>>60 #### 60 Bob gets rent assistance because he's low-income. If he gets a raise of $0.50/hour and works 40 hours a week, how much more will he actually earn a week if his housing benefit is reduced by $60/month? First find the total increase in Bob's earnings: $0.50/hour * 40 hours/week = $<<0.50*40=20>>20/week Then find the weekly decrease in Bob's housing assistance: $60/month / 4 weeks/month = $<<60/4=15>>15/week Then subtract the lost assistance from the increased wages to find Bob's net increase in money: $20/week - $15/week = $<<20-15=5>>5/week #### 5 She sold twice as many boxes on Tuesday as she did on Wednesday, and she sold twice as many boxes on Wednesday as she did on Thursday. If Kim sold 1200 boxes of cupcakes on Thursday, how many boxes did she sell on Tuesday? Kim sold 1200*2 = <<1200*2=2400>>2400 boxes of cupcakes on Wednesday. Kim sold 2400*2 = <<2400*2=4800>>4800 boxes of cupcakes on Tuesday. #### 4800 Jo reads at a steady pace. Her current book has 210 pages. Now, she is at page 90. An hour ago, she was at page 60. For how many hours will she be reading the book? She reads 90-60=<<90-60=30>>30 pages in an hour. She needs to read 210-90=<<210-90=120>>120 more pages. For an additional 120 pages, she will need 120/30=<<120/30=4>>4 hours. #### 4 James decides he needs to start eating more vegetables. He starts by eating a quarter pound of asparagus and a quarter pound of broccoli per day. After 2 weeks, he doubles that amount and adds 3 pounds of kale per week. How many pounds of vegetables does he eat a week after adding the kale? He starts with .25+.25=<<.25+.25=.5>>.5 pounds of vegetables a day After doubling that it goes to .5*2=<<.5*2=1>>1 pound a day So he eats 1*7=7 pounds of asparagus and broccoli per week So he eats a total of 7+3=<<7+3=10>>10 pounds of vegetables a week #### 10
