While on vacation in Hawaii, Steve and Georgia decided to ship pineapples to their home. Each pineapple costs $1.25 and they buy a dozen. It will cost $21.00 to ship all of them to their home. How much will each pineapple end up costing them?

They bought 12 pineapples for $1.25 apiece so 12*1.25 = $

<<12*1.25=15.00>>15.00 The pineapples cost $15.00 and it will cost $21.00 to ship so all total, it costs 15+21 = $<<15+21=36.00>>36.00 In total it costs $36.00 to ship home a dozen pineapples so each pineapple costs 36/12 = $<<36/12=3.00>>3.00 apiece #### 3 Charles is jogging while listening to his favorite album. He runs at 6 MPH when he's got music on and 4 MPH when he doesn't. His album is 40 minutes long. How many minutes will it take him to jog 6 miles? He runs at .1 miles per minute because 6 / 60 = <<6/60=.1>>.1 While the album is playing he can run 4 miles because 40 x .1 = <<40*.1=4>>4 He has to run 2 miles without the album because 6 - 4 = <<6-4=2>>2 Without music he runs 1/15 miles per minute because 4 / 60 = 1/15 He will run the remaining 2 miles in 30 minutes because 2 / (1/15) = <<2/(1/15)=30>>30 It will take him 70 minutes in total because 40 + 30 =<<40+30=70>>70 #### 70 Hershel has 10 betta fish and 15 goldfish in a bowl. His friend Bexley brings him 2/5 times as many betta fish and 1/3 times as many goldfish. If Hershel gifts his sister 1/2 of the fish, calculate the total number of fish he has remaining in the bowl. Bexley gives Hershel 2/5*10 = <<2/5*10=4>>4 betta fish. The total number of betta fish in the bowl is now 4+10 = <<4+10=14>>14 He also gives Hershel 1/3*15 = <<1/3*15=5>>5 goldfish The total number of goldfish in the bowl is now 15+5 = <<15+5=20>>20 Counting the betta fish and goldfish, Hershel now has a total of 14 + 20 = <<14+20=34>>34 fish When he gives his sister half of the fish, the remaining half is 34/2 = <<34/2=17>>17 fish #### 17 Rory collects rainwater. He has 100 L of rainwater in his tank. During a heavy rainstorm, water flows into the tank at a rate of 2 L/min for 90 minutes. How much water is in the tank at the end of the heavy rain? During the heavy rain, the tank collects 2 * 90 = <<2*90=180>>180 L of water The tank has a total of 100 + 180 = <<100+180=280>>280 L of water #### 280 Bryan's score on a math exam is 20. Jen scored 10 more than Bryan while Sammy scored 2 fewer than Jen. If the math exam has 35 points in all, how many mistakes did Sammy make? Jen scored 20 + 10 = <<20+10=30>>30 on the exam. Sammy scored two less, so his score was30 - 2 = <<30-2=28>>28. Thus, Sammy made 35 - 28 = <<35-28=7>>7 mistakes. #### 7 Mabel has 5 daisies in her garden, and each daisy has 8 petals. If she gives 2 daisies to her teacher, how many petals does she have on the remaining daisies in her garden? The total number of petals Mabel has in her garden is 5 x 8 = <<5*8=40>>40 petals. The total number of petals that Mabel gives to her teacher is 2 x 8 = <<2*8=16>>16 petals. The total number of petals remaining in her garden is 40 - 16 = <<40-16=24>>24 petals. #### 24 Nina has received a scholarship worth $8000 less than Kelly's amount. Kelly received a scholarship worth twice the amount Wendy received. How much money did they receive in scholarship together if Wendy received a scholarship worth $20000? If Wendy received a scholarship worth $20000, Kelly, who received twice as much, received 2*$20000 = $40000 Together, Wendy and Kelly received Scholarship worth $40000+$20000 = $<<40000+20000=60000>>60000 Nina received a scholarship worth $8000 less than Kelly's amount, a total of $40000-$8000 = $32000 Together, the three received scholarship worth $32000+$60000 = $<<32000+60000=92000>>92000 #### 92000 On Thursday Walmart sold 210 pounds of ground beef. On Friday they sold twice that amount. On Saturday they only sold 150 pounds. What was the average amount of beef sold per day? On Friday Walmart sold 2 * 210 pounds = <<2*210=420>>420 pounds. For all three days Walmart sold 210 + 420 + 150 pounds = <<210+420+150=780>>780 pounds. The average amount of beef sold per day is 780 pounds / 3 days = <<780/3=260>>260 pounds. #### 260 Wilson decides to go sledding on some nearby hills. On the 2 tall hills, he sleds down them 4 times each and on the 3 small hills, he sled down them half as often as he sleds down the tall hills. How many times did he sled down the hills? On the tall hills, he sleds down 2 tall hills * 4 times per tall hill = <<2*4=8>>8 times. He sleds down the small hills half as often so he sleds down each hill 4 times per tall hill / 2 = <<4/2=2>>2 times per small hill. On the small hills, he sleds down 3 small hills * 2 times per small hill = <<3*2=6>>6 times. So in total, Wilson sled down the hills 8 times on tall hills + 6 times on small hills = <<8+6=14>>14 times. #### 14 Bea and Dawn both have a lemonade stand. Bea sells her lemonade at 25 cents while Dawn sells hers at 28 cents. If Bea sold 10 glasses and Dawn sold 8 glasses, how much more money (in cents) did Bea earn than Dawn? Bea's sales amount to $0.25/glass x 10 glasses = 250 cents. Dawn's sales amount to $0.28/glass x 8 glasses = 224 cents. So, Bea earned $2.50 - $2.24 = 26 cents more than Dawn. #### 26
