Sandra wants to buy some sweets. She saved $10 for this purpose. Her mother gave her an additional $4, and her father twice as much as her mother. One candy costs $0.5, and one jelly bean $0.2. She wants to buy 14 candies and 20 jelly beans. How much money will she be left with after the purchase?

Sandra's father gave her $4 * 2 = $

<<4*2=8>>8. So Sandra has in total $8 + $4 + $10 = $<<8+4+10=22>>22. She wants 14 candies, so she is going to pay 14 candies * $0.50/candy = $<<14*0.5=7>>7 for them. She wants also 20 jellybeans, and they're going to cost 20 jellybeans * $0.20/jellybean = $<<20*0.2=4>>4. So after the purchase, she will be left with $22 - $4 - $7 = $<<22-4-7=11>>11. #### 11 At the same store, Peter bought 2 pairs of pants and 5 shirts for $62 total, and Jessica bought 2 shirts for $20 total. Each pair of pants cost the same price, and each shirt cost the same price. How much does 1 pair of pants cost? The shirts each cost $20 / 2 shirts = $<<20/2=10>>10. Let X be the pants' cost. Peter bought 2 pairs of pants and 5 shirts for 2*X + 5 shirts * $10/shirt = $62. Subtracting $50 from both sides, we get 2*X = $12. Dividing both sides by 2, we get X = $6. #### 6 The ratio of books to pens that Arlo has to buy for his school supplies is 7:3. If he bought a total of 400 stationery from the store, calculate the number of books he bought. The total ratio representing the stationery that Arlo has to buy for his school supplies is 7+3 = <<7+3=10>>10 The fraction representing the number of books that Arlo bought is 7/10, and since he bought a total of 400 books and pens, he bought 7/10*400 = <<7/10*400=280>>280 books. #### 280 Freddie and his team are collecting blankets for three days to be donated to the Children Shelter Organization. There are 15 people on the team. On the first day, each of them gave 2 blankets. On the second day, they tripled the number they collected on the first day by asking door-to-door. On the last day, they set up boxes at schools and got a total of 22 blankets. How many blankets did they collect for the three days for donation? They collected 15 x 2 = <<15*2=30>>30 blankets on the first day. Freddie and his team collected 30 x 3 = <<30*3=90>>90 blankets on the second day. They collected a total of 90 + 22+30 = <<90+22+30=142>>142 for three days. #### 142 There were 133 people at a camp. There were 33 more boys than girls. How many girls were at the camp? If there were 33 fewer boys at camp, there would be the same number of both boys and girls or 133 - 33 = <<133-33=100>>100 people. That means that there were 100 / 2 = <<100/2=50>>50 girls at the camp. #### 50 Hunter needs to make a square patch of land whose perimeter is twice as large as a rectangular patch of land. If the rectangular patch of land has a length of 400 feet and a width of 300 feet, calculate the length of one side of the square patch of land. If the rectangular patch of land measures 400 feet by 300 feet, the total length around it or its perimeter is given by 2 * 400 + 2 * 300 = 800 + 600 = <<2*400+2*300=1400>>1400 The square patch's perimeter is double that length, so it's 1400 * 2 = <<1400*2=2800>>2800 Since the square has four equal sides, one side of the square patch of land will have a length of 2800/4 = <<2800/4=700>>700 feet #### 700 On Friday, Addison sold 181 raffle tickets for a fundraiser. She sold twice as many on Saturday. On Sunday, she sold 78 raffle tickets. How many more raffle tickets were sold on Saturday than Sunday? Addison sold 181 x 2 = <<181*2=362>>362 raffle tickets on Saturday. She sold 362 on Saturday – 78 on Sunday = <<362-78=284>>284 more on Saturday than Sunday. #### 284 Mia is a student. In her final year, she spent 1/5 of her day watching TV and 1/4 of the time left on studying. How many minutes did she spend studying each day? If Mia spent 1/5 of her day watching TV, her remaining time in a day is 5/5 – 1/5 = 4/5 for other things. So, the time left is 24 * 4/5 = <<24*4/5=19.2>>19.2 hours The time spent studying is 19.2 /4 = <<19.2/4=4.8>>4.8 hours. In minutes, that is 4.8 * 60 = <<4.8*60=288>>288 minutes #### 288 Maryann spends seven times as long doing accounting as calling clients. If she worked 560 minutes today, how many minutes did she spend calling clients? Let a be the amount of time Maryann spends doing accounting and c be the amount of time she spends calling clients: We know that a + c = 560 and a = 7c. Substituting the second equation into the first equation, we get 7c + c = 560 Combining like terms, we get 8c = 560 Dividing both sides by 8, we get c = 70 #### 70 Tommy has 13 items in his pencil case. The pens are twice as many as the pencils and there's one eraser. How many pencils are there? There are 13 items - 1 eraser = <<13-1=12>>12 pens and pencils. There are 12 items / 3 = <<12/3=4>>4 pencils. #### 4
