Steve has 2 boxes of pencils with 12 pencils in each box. He gave Matt 3 more pencils than he gave to Lauren. If Steve gave 6 pencils to Lauren, how many pencils does he have left?

Steve started with 2 * 12 =

<<2*12=24>>24 pencils. He gave Matt 6 + 3 = <<6+3=9>>9 pencils. After giving away the pencils, Steve will have 24 – 9 – 6 = <<24-9-6=9>>9 pencils left. #### 9 Charlotte, Lisa, and Patricia have a joint baseball collection. One of their friends is selling a rare baseball card for $100 on his website. Not wanting to miss such a rare opportunity, they have pooled all their money to buy the card. Patricia has $6. Lisa has five times Patricia’s money, but double Charlotte’s. How much more money do they require? Since Patricia has 6 dollars, then Lisa has 6 * 5 = <<6*5=30>>30 dollars. Patricia’s money is double Charlotte’s, meaning that Charlotte has 30/2 = <<30/2=15>>15 dollars. Adding up all the money they have gives a total of 6 + 30 + 15 = <<6+30+15=51>>51 dollars. Since the rare card costs 100 dollars, the girls require an additional 100 -51 = <<100-51=49>>49 dollars #### 49 A smartphone seller is offering a discount of 5% off for customers who buy at least 2 smartphones at once. Melinda, Zoe and Joel want to buy an iPhone X each. If an iPhone X costs $600, how much can they save by pooling their money together and buying three iPhones at once from this seller rather than buying individually? Each iPhone X cost $600 so three iPhone Xs without the discount would cost 3*$600 = $<<3*600=1800>>1800 The discount is 5% and 5% of $1800 is (5/100)*$1800 = $<<5/100*1800=90>>90 which is what they get to save by buying collectively. #### 90 Monica and Michelle are combining their money to throw a party. Monica brings $15. Michelle brings $12. The cake costs 15 dollars, and soda is $3 a bottle. Each bottle of soda has 12 servings and they buy as many bottles of soda as they can afford. If there are 8 total guests, how many servings of soda does each get? They have $27 for the party because 15 + 12 = <<15+12=27>>27 They have $12 for soda because 27 - 15 = <<27-15=12>>12 They can buy 4 bottles of soda because 12 / 3 = <<12/3=4>>4 They have 48 servings of soda because 4 x 12 = <<4*12=48>>48 Each guest gets 6 servings because 48 / 8 = <<48/8=6>>6 #### 6 At a James Bond movie party, each guest is either male (M) or female (F. 40% of the guests are women, 80% of the women are wearing rabbit ears, and 60% of the males are wearing rabbit ears. If the total number of guests at the party is 200, given all this information, what is the total number of people wearing rabbit ears? If 40% of the guests are females, then there are 40/100*200 = <<40/100*200=80>>80 female guests at the party. The number of female guests wearing rabbit ears is 80/100* 80=<<80/100*80=64>>64 The number of male guests is 200 guests - 80 female guests = <<200-80=120>>120. If 60% of the male guests are wearing rabbit ears, then there are 60/100 *120 = <<60/100*120=72>>72 male guests wearing rabbit ears. The total number of guests wearing rabbit ears is 64+72 = <<64+72=136>>136 #### 136 Mary Anne drinks 1/5 of a bottle of sparkling water every night at dinner. If each bottle costs her $2.00, how much does she spend on sparkling water every year? She drinks 1/5 of a bottle of sparkling water every night so over an entire year she drinks .2*365 = <<1/5*365=73>>73 bottles of sparkling water Every bottle costs $2.00 and she drinks 73 bottles a year so she spends 2*73 = $<<2*73=146.00>>146.00 a year on sparkling water #### 146 A long wire is cut into three smaller pieces in the ratio of 7:3:2. If the shortest piece is 16 cm, how long was the entire wire before it was cut? Since the shortest part is consists of 2 parts, then each part is equal to 16 cm/2 = 8 cm. The whole wire was cut into 7 + 3 + 2 = <<7+3+2=12>>12 parts. Hence, the wire was 8 cm x 12 = <<8*12=96>>96 cm long #### 96 At the park, Naomi saw people riding 7 regular bikes and 11 children’s bikes. Regular bikes have 2 wheels and kid’s bikes have 4 wheels. How many wheels did Naomi see at the park? For the regular bikes, there are 7 x 2 = <<7*2=14>>14 wheels. For the children’s bikes, there are 11 x 4 = <<11*4=44>>44 wheels. Altogether, Naomi saw 14 + 44 = <<14+44=58>>58 wheels. #### 58 Rick took off on a road trip for the summer. He traveled to the first destination on his trip, and then from there, he traveled twice the distance to this second destination. The third point on his trip was 40 miles away, which was half the distance he traveled from the beginning to his first destination. The final destination took twice the amount of driving of all the other legs put together. How many miles in total did he travel across all the legs of the trip? If the third leg of Rick's trip was half the distance of the first leg, was 40 miles, this means the first leg was 40*2=<<40*2=80>>80 miles long If the second leg of the trip was twice the distance of the first leg, that means it was 80*2=<<80*2=160>>160 miles long If the fourth leg was equal in distance to the total amount traveled across the first 3 legs, that means it was equal to 40+80+160= <<280=280>>280 miles long This means in total Rick traveled 280+280= <<280+280=560>>560 miles #### 560 Ivy drinks 2.5 liters of water each day. How many bottles of 2-liter water should Ivy buy for her 4 days consumption? For 4 days, Ivy consumes 2.5 x 4 = <<2.5*4=10>>10 liters of water. So Ivy should buy 10/2 = <<10/2=5>>5 bottles of 2-liter water. #### 5
