A person puts $5600 in a bank for two years. Each year he earns interest of 7% of the original amount deposited. How much will this person have in the bank after two years?

The interest that this person will get equals $5600 * 7%/year * 2 years = $

<<5600*7*.01*2=784>>784. After two years the amount found at the bank is $5600 + $784 = $<<5600+784=6384>>6384. #### 6384 Yanni has $0.85. His mother gave him $0.40 in addition. While going to the mall, Yanni found $0.50. He bought a toy that cost $1.6. How much money in cents did Yanni have left? Yanni's mother gave him $0.40 in addition to $0.85 for a total of $0.40+$0.85 = $<<0.40+0.85=1.25>>1.25. Yanni found $0.50 so he had a total of $1.25 + $0.50 = $<<1.25+0.5=1.75>>1.75 Therefore, Yanni had $1.75 - $1.6 = $<<1.75-1.6=0.15>>0.15 left 100 cents make $1 so $0.15 is 100*0.15 = <<100*0.15=15>>15 cents #### 15 Wendi lives on a plot of land that is 200 feet by 900 feet of grassland. She raises rabbits on her property by allowing the rabbits to graze on the grass that grows on her land. If one rabbit can eat enough grass to clear ten square yards of lawn area per day, and Wendi owns 100 rabbits, how many days would it take for Wendi's rabbits to clear all the grass off of her grassland property? One square yard is the same as 3 feet by 3 feet, or 3*3=<<1*3*3=9>>9 square feet. Ten square yards is 9*10=<<10*9=90>>90 square feet. Therefore, 100 rabbits can clear 100*90=<<100*90=9000>>9,000 square feet of grassland per day. A 200 ft by 900 ft area is 200*900=<<200*900=180000>>180,000 square feet. Thus, 180,000 sq ft can be cleared by 100 rabbits in 180,000/9000=<<180000/9000=20>>20 days #### 20 Amy is building 2 3 ft long by 3 ft wide garden beds and 2 4ft long by 3 ft wide garden beds. What is the total sq ft of growing space that she will have? The first bed is 3 feet long by 3 feet wide so it's 3*3 = <<3*3=9>>9 sq ft She's building 2 beds that are this size so that's 2*9 = <<2*9=18>>18 sq ft of growing space The second bed is 4 feet long by 3 feet wide so it's 4*3 = <<4*3=12>>12 sq ft She's building 2 beds that are this size so that's 2*12 = <<2*12=24>>24 sq ft of growing space The smaller beds are 18 sq ft and the larger beds are 24 sq ft for a total of 18+24 = <<18+24=42>>42 sq ft of growing space #### 42 A third of the contestants at a singing competition are female, and the rest are male. If there are 18 contestants in total, how many of them are male? There are 18/3 = <<18/3=6>>6 female contestants. There are 18-6 = <<18-6=12>>12 male contestants. #### 12 A patient is receiving treatment through a saline drip which makes 20 drops per minute. If the treatment lasts 2 hours, and every 100 drops equal 5 ml of liquid, how many milliliters of treatment will the patient receive after the 2 hours have passed? The total of minutes the treatment will take is 2 hours x 60 minutes/hour = <<2*60=120>>120 minutes After 120 minutes has passed the total amount of drops that the patient will receive is 20 drops/minute x 120 minutes = <<20*120=2400>>2400 drops Knowing the number of drops, we know that the patient has taken 2400 drops x 5 ml/100 drops = 120 ml #### 120 A 40-bead necklace is made up of three kinds of beads. There are seven amethyst beads and twice as many amber beads as amethysts. The third beads are turquoise. How many turquoise beads are in the necklace? There are 7 * 2 = <<7*2=14>>14 amber beads. Thus, there are 40 - 7 - 14 = <<40-7-14=19>>19 turquoise beads in the necklace. #### 19 The Martin family goes to the mall to get ice cream. A kiddie scoop is $3. A regular scoop is $4. A double scoop is $6. Mr. and Mrs. Martin each get the regular scoop. Their two children each get the kiddie scoop. Their three teenage children each get double scoops. How much money does Mrs. Martin pay the cashier? The two regular scoops cost $4 x 2 = $<<4*2=8>>8. The two kiddie scoops cost $3 x 2 = $<<3*2=6>>6. The three double scoops cost $6 x 3 = $<<6*3=18>>18. For all the ice creams they ordered, Mrs. Martin pays $8 + $6 + $18 = $<<8+6+18=32>>32. #### 32 Kohen has a business selling apples. Once a week, he orders 10 boxes of apples to add to his stock. If each box has 300 apples and he sells 3/4 of his stock in a certain week, what total number of apples is not sold? In a week, he orders 10 * 300 = <<10*300=3000>>3000 apples. When 3/4 of the stock is sold, the total amount of apples sold becomes 3/4 * 3000 = <<3/4*3000=2250>>2250 apples. The amount of apples remaining is 3000 - 2250 = <<3000-2250=750>>750 apples. #### 750 Matt has 8 baseball cards worth $6 each. If he trades two of them to Jane in exchange for 3 $2 cards and 1 $9 card, how much profit does he make? First find the value of the 2 cards Matt trades: $6/card * 2 cards = $<<6*2=12>>12 Then find the total value of the 3 $2 cards: 3 cards * $2/card = $<<3*2=6>>6 Then subtract the value of the cards Marcus gave up from the value of the cards he gained to find his profit: $9 + $6 - $12 = $<<9+6-12=3>>3 #### 3
