Dylan's mother is throwing a baby shower for her best friend. She is expecting 40 guests, of whom she has cleared the parking lot to park in to, leaving only her car and her husband's jeep in the parking lot. The 40 guests, though, arrive in only 10 cars that they park in the parking lot. If each car has 4 wheels, how many car wheels are there in the parking lot, including both of Dylan's parent's car wheels?

10 cars are parked around for the party, 10 x 4 wheels each car =

<<10*4=40>>40 wheels total. Dylan's parents both have a car with 4 wheels each, 2 x 4 = <<4*2=8>>8 more wheels. Combined, there are 40 + 8 = <<40+8=48>>48 wheels total on the Dylan family property. #### 48 Melissa sells a coupe for $30,000 and an SUV for twice as much. If her commission is 2%, how much money did she make from these sales? First find the total cost of the SUV: $30,000 * 2 = $<<30000*2=60000>>60,000 Then add the cost of the coupe to find the total cost of the cars: $60,000 + $30,000 = $<<60000+30000=90000>>90,000 Multiplying that amount by Melissa's commission rate, we find her earnings are $90,000 * 2% = $<<90000*2*.01=1800>>1800 #### 1800 In North Carolina, Jim bought 10 gallons of gas at $2.00/gallon. He paid $1.00 more per gallon in Virginia where he bought another 10 gallons of gas. How much has he spent on gas? In North Carolina, he bought 10 gallons at $2.00/gallon for a total of 10*2 = $<<10*2=20.00>>20.00 He paid $2.00 a gallon in North Carolina and $1.00 more in Virginia for a total of 2+1 = $<<2+1=3.00>>3.00/gallon He bought 10 gallons at $3.00/gallon in Virginia for a total of 10*3 = $<<10*3=30.00>>30.00 He spent $20.00 in North Carolina and $30.00 in Virginia for total of 20+30 = $<<20+30=50.00>>50.00 #### 50 In Rodrigo's classroom in the morning there are red chairs, yellow chairs, and blue chairs. There are 4 red chairs. There are 2 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. In the afternoon, Lisa borrows 3 chairs. How many chairs are left in Rodrigo's classroom? There are 2 * 4 red chairs = <<2*4=8>>8 yellow chairs. There are 8 yellow chairs - 2 = <<8-2=6>>6 blue chairs. Total in the morning there were 4 red + 8 yellow + 6 blue = <<4+8+6=18>>18 chairs. After Lisa removed chairs there were 18 - 3 chairs = <<18-3=15>>15 chairs remaining. #### 15 In Henry's collection of music CDs, he has 3 more country CDs than rock CDs but twice as many rock CDs as classical CDs. If he has 23 country CDs, how many classical CDs make up his collection? Henry has 23-3=<<23-3=20>>20 rock CDs. Henry has 20/2=<<20/2=10>>10 classical CDs. #### 10 Fabian has three times more marbles than Kyle and five times more than Miles. If Fabian has 15 marbles, how many marbles do Kyle and Miles have together? Kyle has a third of Fabian's number of marbles, so he has 15 / 3 = <<15/3=5>>5 marbles. Miles has a fifth of Fabian's number of marbles, so he has 15 / 5 = <<15/5=3>>3 marbles. Miles and Kyle together have 5 + 3 = <<5+3=8>>8 marbles. #### 8 My 2 cats had 3 female kittens and 2 male kittens. How many cats do I have in total? There are 3+2 = <<3+2=5>>5 kittens If you originally had 2 cats then you now have 2+5 = <<2+5=7>>7 cats in total #### 7 James buys 20 pounds of beef and half that much pork. He uses 1.5 pounds of meat to make meals at his restaurant. Each meal sells for $20. How much money did he make? He bought 20/2=<<20/2=10>>10 pounds of pork So he has 20+10=<<20+10=30>>30 pounds of meat That means he can make 30/1.5=<<30/1.5=20>>20 meals So he makes 20*20=$<<20*20=400>>400 #### 400 A single line is worth 1000 points. A tetris is worth 8 times that much. Tim scored 6 singles and 4 tetrises. How many points did he score? A tetris is worth 8*1000=<<8*1000=8000>>8000 points So he scored 4*8000=<<4*8000=32000>>32000 points from tetrises He also scores 6*1000=<<6*1000=6000>>6000 points from singles So in total he scores 32000+6000=<<32000+6000=38000>>38,000 points #### 38000 Sally sold 20 cups of lemonade last week. She sold 30% more lemonade this week. How many cups of lemonade did she sell in total for both weeks? If Sally sold 30% more lemonade this week, she sold 20 * 30/100 = <<20*30/100=6>>6 more cups this week. This week, Sally sold 20 + 6 = <<20+6=26>>26 cups of lemonade. In total for both weeks, Sally sold 20 + 26 = <<20+26=46>>46 cups of lemonade. #### 46
