A milk teas shop was able to sell a total of 50 cups of milk tea yesterday. Two-fifths of their sales are winter melon flavor, three-tenths are Okinawa flavor, and the rest are chocolate flavor. How many cups of chocolate-flavored milk tea were they able to sell yesterday?

A milk tea shop sold 50 x 2/5 =

<<50*2/5=20>>20 cups of winter melon-flavored milk tea. They sold 50 x 3/10 = <<50*3/10=15>>15 cups of Okinawa-flavored milk tea. So they sold a total of 20 + 15 = <<20+15=35>>35 cups of winter melon and Okinawa flavors milk tea. Therefore, they sold 50 - 35 = <<50-35=15>>15 cups of chocolate-flavored milk tea. #### 15 Reggie is playing marbles with his friend. His friend arrives with 100 marbles. Each game, they bet ten marbles and whoever wins gets to keep all the marbles. After 9 games, Reggie has 90 marbles. How many games has he lost? Reggie has lost 10 marbles because 100 - 90 = <<100-90=10>>10 Since each game was worth 10 marbles, Reggie has lost 1 game #### 1 Marcy can make 3 spears out of a sapling and 9 spears out of a log. How many spears can she make out of 6 saplings and a log? First find the total number of spears she makes from saplings: 3 spears/sapling * 6 saplings = <<3*6=18>>18 spears Then add the number she makes from the log: 18 spears + 9 spears = <<18+9=27>>27 spears #### 27 Denny is planning to build a modular home. A 400 square foot Kitchen module costs $20000 and a 150 square foot bathroom module costs $12,000. All other modules cost $100 per square foot. If Denny plans to build a 2,000 square foot modular home containing one kitchen and two bathrooms, how much will it cost, in dollars? The kitchen and two bathroom modules will take up 400+150+150=<<400+150+150=700>>700 sq. ft. of the 2000 sq. ft. of space. Thus, the remaining modular space is 2000-700=<<2000-700=1300>>1300 sq. ft. Cost of the kitchens and bathrooms is $20,000+$12,000+$12,000=$<<20000+12000+12000=44000>>44,000. The cost of the other 1300 sq. ft. of space is 1300*$100=$<<1300*100=130000>>130,000. In total, the cost of the complete 2000 sq.ft. modular home with one kitchen and two bathrooms is $44,000 + $130,000 = $<<44000+130000=174000>>174,000. #### 174,000 Hannah has 5 times as many dolls as her sister. Her sister has 8 dolls. How many dolls do they have altogether? Hanna has 5 times as many dolls as her sister, so 5 x 8 dolls = <<5*8=40>>40 dolls. Together, they have 8 dolls + 40 dolls = <<8+40=48>>48 dolls. #### 48 Dale just learned how to make homemade macaroni and cheese. He decided to make a big batch for his family reunion. The original recipe calls for 2 pounds of pasta and serves 7 people. Dale's family reunion will have 35 people. How many pounds of pasta does Dale need to buy? Dale's batch needs to be 35 ÷ 7 = <<35/7=5>>5 times larger than the original recipe. Dale needs 2 × 5 = <<2*5=10>>10 pounds of pasta. #### 10 Justin needs to read at least 100 pages or more of his book in one week to pass his class. He has read 10 pages already on the first day. Assuming he reads twice the amount of pages as the first day each day in the remaining 6 days, how many pages will he have read after the week is over? 10 pages per day on day 1 * 2 = <<10*2=20>>20 pages per day for days 2 through 7 20 * 6 remaining days = <<20*6=120>>120 pages total from days 2 through 7 10 pages day 1 + 120 pages days 2 through 7 = <<10+120=130>>130 total pages read in one week #### 130 Grant decided to sell his baseball gear since he was now playing football. He sold his baseball cards for $25. He got $10 for his baseball bat and agreed to sell his $30 baseball glove at 20% off. He also sold both pair of his baseball cleats for $10 each. How much money did Grant make? The baseball glove was originally $30 and he agreed to take 20% off so 30*.20 = $<<30*.20=6.00>>6.00 off If you take the price of the glove and subtract the discount then $30-$6 = $<<30-6=24.00>>24.00 He sold 2 pair of shoes for $10 each so 2*$10 = $<<2*10=20.00>>20.00 He got $25 for the cards, $10 for the bat, $24.00 for the glove and $20 for the shoes so he made $25+$10+$24+$20 = $<<25+10+24+20=79.00>>79.00 #### 79 John weighs 220 pounds when he starts exercising. He manages to lose 10% of his body weight. He then gains back 2 pounds. How much does he weigh at the end? He lost 220*.1=<<220*.1=22>>22 pounds So after gaining some weight back he was 22-2=<<22-2=20>>20 pounds lighter than before So his weight is 220-20=<<220-20=200>>200 pounds #### 200 Steve's new book sells 1,000,000 copies. He got an advance to pay for 100,000 copies. He gets $2 for each copy of the book sold. His agent takes 10% of that. How much money did he keep not counting the money from the advance? He sold 1,000,000-100,000=<<1000000-100000=900000>>900,000 not counting the advance So he made 900,000*2=$<<900000*2=1800000>>1,800,000 from selling the books His agent took 1,800,000*.1=$<<1800000*.1=180000>>180,000 That means he kept 1,800,000-180,000=$<<1800000-180000=1620000>>1,620,000 #### 1620000
