Mr. Callen bought 10 paintings at $40 each and 8 wooden toys at $20 each from the crafts store to resell at a profit. However, when he sold the items, the selling price of a painting was 10% less and the selling price of a hat 15% less. Calculate the total loss Mr. Callen made from the sale of the items.

If he sold a painting at a 10% loss, then he made a 10/100*$40 = $

<<10/100*40=4>>4 loss on each painting. since he bought 10 paintings, the total loss he made from selling the paintings is 10*$4 = $<<10*4=40>>40 He also made a loss of 15/100*20 = $<<15/100*20=3>>3 loss from selling each wooden toy. Since he bought 8 wooden toys, the total loss he made was 3*8 = $<<8*3=24>>24 In total, Mr. Callen made a loss of $40+$24 = $<<40+24=64>>64 from the sales of the items. #### 64 An electronic shop offers smartphones for $300 each, personal computers for $500 more than smartphones, and advanced tablets for the sum of the prices of a smartphone and personal computer. How much do you have to pay to buy one of each of the three mentioned products? The price of a personal computer is $300 + $500 = $<<300+500=800>>800. The price of an advanced tablet would be $300 + $800 = $<<300+800=1100>>1100. To buy each of these products, you would have to pay $300 + $800 + $1100 = $<<300+800+1100=2200>>2200. #### 2200 Coral is reading a book that is 600 pages long. She reads half of it in the first week, and 30 percent of the remaining pages the second week. How many pages must she read the third week in order to finish the book? Week 1:600/2=300 600-300=<<600-300=300>>300 pages remain Week 2:300(.30)=90 pages 300-90=<<300-90=210>>210 pages remain Week 3:210 pages #### 210 John eats a bag of chips for dinner and then eats twice as many after dinner. How many bags of chips did he eat? He ate 2 * 1 = <<2*1=2>>2 bags after dinner So he ate 2 + 1 = <<2+1=3>>3 bags of chips #### 3 Jenny had $24 left after spending 3/7 of her money. How much is half of her original amount of money? Jenny spent 1 - 3/7 = 4/7 of her money. Since 4/7 is equal to $24, then 1/7 is equal to $24/4 = $6. So, Jenny originally had $6 x 7 = $<<6*7=42>>42. Therefore, half of her original amount of money is $42/2 = $<<42/2=21>>21. #### 21 Tim has 30 toads. Jim has 20 more toads than Tim does. Sarah has twice as many toads as Jim does. How many toads does Sarah have? Jim has 30+20 = <<30+20=50>>50 toads Sarah has 50*2 = <<50*2=100>>100 toads #### 100 Jed is 10 years older than Matt. In 10 years, Jed will be 25 years old. What is the sum of their present ages? Jed is 25 - 10 = <<25-10=15>>15 years old now. So, Matt is 15 - 10 = <<15-10=5>>5 years old now. Thus, the sum of their present ages is 15 + 5 = <<15+5=20>>20. #### 20 Shara collects shells. She had 20 shells before she went on vacation. On vacation, she found 5 shells per day for 3 days. Then he found 6 shells on the fourth day. How many shells does she have now? Shara collected 5 x 3 = <<5*3=15>>15 shells for 3 days. So she collected 15 + 6 = <<15+6=21>>21 shells rom her vacation. Thus, she now has a total of 20 + 21 = <<20+21=41>>41 shells. #### 41 Whitney’s mom gave her two $20 bills to spend at the school book fair. Whitney has decided to buy 2 posters, 3 notebooks, and 2 bookmarks. Each poster costs $5, each notebook costs $4, and each bookmark costs $2. How much money, in dollars, will Whitney have left over after the purchase? Whitney is buying 2 posters for $5 each, so the posters will cost 2*$5= $<<2*5=10>>10 total cost for posters. Whitney is buying 3 notebooks for $4 each, so the notebooks will cost 3*$4= $<<3*4=12>>12 total cost for notebooks. Whitney is buying 2 notebooks for $2, so the bookmarks 2*$2= $<<2*2=4>>4 total cost for bookmarks. Since Whitney is paying $10 for posters, $12 for notebooks, and $4 for bookmarks, her total purchase will cost $10+$12+$4= $<<10+12+4=26>>26 total purchase cost. Whitney’s mom gave her 2 $20 bills, so she will be paying with 2*$20=$<<2*20=40>>40 total payment. Since Whitney is paying with $40 and her purchase cost will be $26, she will have $40-$26= $<<40-26=14>>14 left over after the purchase. #### 14 John jogs at a speed of 4 miles per hour when he runs alone, but runs at 6 miles per hour when he is being dragged by his 100-pound German Shepherd dog. If John and his dog go on a run together for 30 minutes, and then John runs for an additional 30 minutes by himself, how far will John have traveled? John runs at 6 miles per hour for 0.5 hours, for a distance of 6*0.5=<<6*0.5=3>>3 miles. Then John runs at 4 miles per hour for 0.5 hours, for a distance of 4*0.5=<<4*0.5=2>>2 miles. In total, John runs 3+2=<<3+2=5>>5 miles. #### 5
