Ray has 95 cents in nickels. If Ray gives 25 cents to Peter, and twice as many cents to Randi as he gave to Peter, how many nickels does Ray have left?

Ray has 95 cents in nickels. If Ray gives 25 cents to Peter, and twice as many cents to Randi as he gave to Peter, how many nickels does Ray have left?

Ray gave 25*2 =

<<25*2=50>>50 cents to Randi. Ray has 95-25-50 = <<95-25-50=20>>20 cents in nickels left. Ray has 20/5 = <<20/5=4>>4 nickels. #### 4 Mac loves the shape of quarters and is willing to trade money for them, even if he loses value. He tells his brother that he will trade him 3 dimes for a quarter or 7 nickels. He trades for 20 quarters with dimes and 20 quarters with nickels. How many dollars did Mac lose? Three dimes is equal to $.3 because 3 x .1 = <<3*.1=.3>>.3 Seven nickels is equal to $.35 because 7 x .05 = <<7*.05=.35>>.35 Each time he trades with dimes he lose $.05 because .3 - .25 = <<.3-.25=.05>>.05 Each time he traded with nickels he lost $.1 because .35 - .25 = <<.35-.25=.1>>.1 He lost $1 from trading with dimes because 20 x .05 =<<20*.05=1>>1 He lost $2 from trading with nickels because 20 x .1 = <<20*.1=2>>2 He lost $3 total because 1 + 2 = <<1+2=3>>3 #### 3 Carmen is counting the cars that pass by her window. All the cars are either white, black, or red. She sees 50 trucks and 40 cars. Half the trucks are red, and another 20% are black. If she picks one car at random, what is the percentage chance it's a white truck, rounded to the nearest integer? First find the total number of vehicles Carmen counted: 50 trucks + 40 cars = <<50+40=90>>90 vehicles Then find the number of trucks that were red: 50 trucks / 2 = <<50/2=25>>25 trucks Then find the number of trucks that were black: 50 trucks * .2 = <<50*.2=10>>10 trucks Then subtract the red and black trucks from the total number of trucks to find the number of white trucks: 50 trucks - 25 trucks - 10 trucks = <<50-25-10=15>>15 trucks Then divide the number of white trucks by the number of vehicles and multiply by 100% to find the percentage of vehicles that are white trucks: 15 trucks / 90 vehicles * 100% = 16.66...%, which rounds up to 17%. #### 17 Darlene's car gets 20 miles/gallon. Martha's car gets half as many miles per gallon as Darlene’s car. How many gallons does Martha’s car require to make a 300-mile trip? Martha’s car gets 20/2 = <<20/2=10>>10 miles per gallon. Total gallons Martha’s car requires is 300/10 = <<300/10=30>>30 gallons. #### 30 Miggy's mom brought home 3 bags of birthday hats. Each bag has 15 hats. Miggy accidentally tore off 5 hats. During the party, only 25 hats were used. How many hats were unused? There are a total of 15 x 3 = <<15*3=45>>45 hats in 3 bags. Since 5 tore off, only 45 - 5 = <<45-5=40>>40 hats were left. Thus, 40 - 25 = <<40-25=15>>15 hats were unused. #### 15 There are many CDs in the store. The rock and roll CDs are $5 each, the pop CDs are $10 each, the dance CDs are $3 each, and the country CDs are $7 each. Julia wants to buy 4 of each, but she only has 75 dollars. How much money is she short? Rock and Roll CDs will be 5*4 = <<5*4=20>>20 dollars. Pop CDs will be 10*4 = <<10*4=40>>40 dollars. Dance CDs will be 3*4 = <<3*4=12>>12 dollars. Country CDs will be 7*4 = <<7*4=28>>28 dollars. In total Julia would need 20+40+12+28 = <<20+40+12+28=100>>100 dollars. Julia is short 100-75 = <<100-75=25>>25 dollars. #### 25 Bob and Kate went to a restaurant for dinner. After they were done eating the waitress gave a $30 bill to Bob and a $25 bill to Kate, but told them they were eligible for special discounts; 5% for Bob, 2% for Kate. Considering the discounts, how much do they have to pay in total? 5% of $30 is (5/100)*30 = $<<(5/100)*30=1.5>>1.5 The dollar amount of Bob's discount is $1.5 so he will pay $30-$1.5 = $28.5 2% of $25 is (2/100)*$25 = $<<2/100*25=0.5>>0.5 The dollar amount of Kate's discount is $0.5 so she will pay $25-$0.5 = $<<25-0.5=24.5>>24.5 Altogether they will pay $28.5+$24.5 = $<<28.5+24.5=53>>53 #### 53 After Martha went grocery shopping she had 4 bottles of juice in the refrigerator and 4 bottles in the pantry. During the week Martha bought 5 more bottles of juice. If Martha and her family drank 3 bottles of juice during the week, how many bottles are left? Martha had 4 bottles of juice in the pantry + 4 bottles in the refrigerator = <<4+4=8>>8 bottles of juice. After Martha went shopping she added 5 bottles of juice to the + 8 bottles she already had = <<5+8=13>>13 bottles of juice. Martha and her family drank 3 bottles of juice during the week from the 13 they had, 13 - 3 = <<13-3=10>>10 bottles left. #### 10 A floral shop had a three day sale on rose bouquets. On Monday, they sold 12 bouquets. On Tuesday, they sold three times that many bouquets. On Wednesday it rained all day and they only sold a third of what they did the day before. How many bouquets did they sell during the three day sale? On Tuesday they sold 12*3=<<12*3=36>>36 bouquets On Wednesday they only sold 36/3=<<36/3=12>>12 bouquets In total they sold 12+36+12=<<12+36+12=60>>60 bouquets #### 60 Jennifer wants to go to a museum. There is one 5 miles away from her home and one 15 miles away. If Jennifer goes to both museums on two separate days, how many miles total will she travel? Jennifer's home is 5 miles away from the first museum, so the round trip back and forth is 5 miles there + 5 miles back = <<5+5=10>>10 miles altogether. On another day Jennifer goes to a museum 15 miles away + 15 miles to return home = <<15+15=30>>30 miles total. Combined, Jennifer travels 10 miles on the first day + 30 miles on the second day = <<10+30=40>>40 miles Jennifer travels total. #### 40
