Mitch is baking a cake and needs 3 cups of flour and two cups of sugar. He doesn't have a one cup scoop, only a 1/3 cup scoop. How many total scoops will he need?

He needs 9 scoops of flour because 3 / (1/3) =

<<3/(1/3)=9>>9 He needs 6 scoops of sugar because 2 / (1/3) = <<2/(1/3)=6>>6 He needs 15 total scoops because 9 + 6 = <<9+6=15>>15 #### 15 Tyler has $100. If he buys 8 scissors for $5 each and 10 erasers for $4 each, how much of his money remains? 8 * $5 = $<<8*5=40>>40 is the price of 8 scissors. 10 * $4 = $<<10*4=40>>40 is the price of 10 erasers. You can find the total price by adding the cost of the scissors and erasers: $40 + $40 = $<<40+40=80>>80 $100 - $80 = $<<100-80=20>>20 is the remaining amount of his money. #### 20 Emma has saved $230 in her bank account. She withdrew $60 to buy a new pair of shoes. The next week, she deposited twice as much money as she withdrew. How much is in her bank account now? Emma had $230 - $60 = $<<230-60=170>>170 left in her bank account after she withdrew $60. The next week, she deposited $60 x 2 = $<<60*2=120>>120. Hence, she now has a total of $170 + $120 = $<<170+120=290>>290 in her bank account. #### 290 Martha has 19 butterflies in her collection. She has twice as many blue butterflies as yellow butterflies. The rest of her butterflies are black. If Martha has 6 blue butterflies, how many black butterflies does she have? Martha has 6/2=<<6/2=3>>3 yellow butterflies. Martha has 6+3=<<6+3=9>>9 blue and yellow butterflies. Martha has 19-9=<<19-9=10>>10 black butterflies. #### 10 Jean and her three friends are playing a game of dominoes. There are 28 dominoes in the set, and Jean wants each player to receive the same number of dominoes. How many dominoes will Jean and her friends each receive? There are 1 + 3 = <<1+3=4>>4 of them playing games of dominoes. Thus, each of them will receive 28/4 = <<28/4=7>>7 dominoes. #### 7 Jenny is older than Charlie by five years, while Charlie is older than Bobby by three years. How old will Charlie be when Jenny becomes twice as old as Bobby? Jenny is older than Charlie by 5 years who is older than Bobby by 3 years, so Jenny is older than Bobby by 5+3 = <<8=8>>8 years Jenny will be twice as old as Bobby when he is 8*2 = 16 years old Jenny is 5 years older than Charlie so when Jenny is 16, Charlie will be 16-5 = 11 years old #### 11 The school has 14 boys and 10 girls. If 4 boys and 3 girls drop out, how many boys and girls are left? There are 14 boys - 4 boys = <<14-4=10>>10 boys left. There are 10 girls - 3 girls = <<10-3=7>>7 girls left. In total there are 10 boys + 7 girls = <<10+7=17>>17 boys and girls left. #### 17 Jack has $43 in his piggy bank. He also gets an allowance of $10 a week. If Jack puts half of his allowance into his piggy bank every week, after 8 weeks how much will Jack have in his piggy bank? Jack saves $10 / 2 = $<<10/2=5.00>>5.00 a week. Over 8 weeks Jack saves $5.00/week x 8 weeks = $<<5.00*8=40.00>>40.00 In total Jack has $43.00 + $40.00 = $<<43+40=83.00>>83.00 dollars in his piggy bank #### 83 A man loves to go hiking. He knows that he has to pack about .5 pounds of supplies for every mile he hikes. He plans to go for a very long hike. He knows that he can get 1 resupply during the hike that will be 25% as large as his first pack. He can hike at a rate of 2.5 mph. He is going to hike 8 hours a day for 5 days. How much does he need to bring with his first pack? He is going to hike 8*=40 hours That means he will be hiking for 40*2.5=<<40*2.5=100>>100 miles So he needs 100*.5=<<100*.5=50>>50 pounds of supplies With the resupply he can get up to 1+.25=<<1+.25=1.25>>1.25 times his initial pack That means his initial pack has to weigh 50/1.25=<<50/1.25=40>>40 pounds #### 40 Scout delivers groceries on the weekends.
