A parking area near Peter's house is 4 stories tall. There are 4 open parking spots on the first level. There are 7 more open parking spots on the second level than on the first level, and there are 6 more open parking spots on the third level than on the second level. There are 14 open parking spots on the fourth level. How many open parking spots are there in all?

The number of open parking spots on the second level is 4 spots + 7 spots =

<<4+7=11>>11 spots. The number of open parking spots on the third level is 11 spots + 6 spots = <<11+6=17>>17 spots. There are 4 spots + 11 spots + 17 spots + 14 spots = <<4+11+17+14=46>>46 open parking spots in all. #### 46 Anna sold 36 glasses of plain lemonade for $0.75 each. If she made $16 total from selling strawberry lemonade, how much more did she make from plain lemonade than strawberry? First find Anna's total earnings from the plain lemonade: 36 glasses * $0.75/glass = $<<36*0.75=27>>27 Then subtract her earnings from the strawberry lemonade to find the difference: $27 - $16 = $<<27-16=11>>11 #### 11 For every 5 people that attend a poetry class, the teacher gives one of the students a lollipop. If 45 people show up for class, then another 15 come in a while later, how many lollipops did the teacher give away? The teacher has 45 + 15 = <<45+15=60>>60 people come in total For every 5 people, a lollipop is given away so there are 60 / 5 = <<60/5=12>>12 groups of 5 people and 12 lollipops given away #### 12 There is a pie-eating contest at school. Adam eats three more pies than Bill. Sierra eats twice as many pies as Bill. If Sierra ate 12 pies, how many pies were eaten in total? Bill ate 12 / 2 = <<12/2=6>>6 pies. Adam ate 6 + 3 = <<6+3=9>>9 pies. They ate a total of 6 + 9 + 12 = <<6+9+12=27>>27 pies. #### 27 A 1000 car parking lot is divided into 3 sections. There are 320 spaces in section 1, and 200 more in section 2 than in section 3. How many spaces are made available in section 2 of the parking lot? There are a total of 1000 spaces - 320 spaces = <<1000-320=680>>680 spaces in both sections 2 and 3. Let the number of spaces in section 3 be x. The number of spaces in section 2 = x + 200. We know that 320 + x + 200 + x = 1000. Combining like terms, we get 2x = 480 Dividing both sides by 2 produces x = 240. The number of spaces in section 2 is 240 + 200 = <<240+200=440>>440. #### 440 Mo is buying valentine's day cards for the class. There are 30 students and he wants to give a Valentine to 60% of them. They cost $2 each. If he has $40, what percentage of his money will he spend on Valentine? He needs 18 valentine's cards because 30 x .6 = <<30*.6=18>>18 He will spend $36 on these because 18 x 2 = <<18*2=36>>36 The proportion of his income spent is .9 because 36 / 40 = <<36/40=.9>>.9 This is 90% of his income because .9 x 100 = <<.9*100=90>>90 #### 90 In a basketball game, Cyrus made exactly eighty percent of the shots he attempted. He attempted twenty shots. How many times did he miss the shots? Cyrus made 20 x 80/100 = <<20*80/100=16>>16 shots. So, he missed 20 - 16 = <<20-16=4>>4 shots. #### 4 Tim sleeps 6 hours per day for 5 days a week and 10 hours a day for the other 2. How much total sleep does he get? He gets 6*5=<<6*5=30>>30 hours of sleep on 5 days He gets 10*2=<<10*2=20>>20 hours the other days So he got 30+20=<<30+20=50>>50 hours #### 50 The town of Belize has 400 homes. One fourth of the town's homes are white. One fifth of the non-white homes have a fireplace. How many of the non-white homes do not have a fireplace? There are 400/4 = <<400/4=100>>100 white homes in Belize. There are 400-100 = <<400-100=300>>300 non-white homes in Belize. There are 300/5 = <<300/5=60>>60 non-white homes that have a fireplace. There are 300-60 = <<300-60=240>>240 non-white homes that do not have a fireplace. #### 240 Janice gave all three dozens of pebbles from her trip to her friends. Each of her friends got 4 pebbles. How many friends received pebbles? Three dozens of pebbles are equal to 3 x 12 = <<3*12=36>>36 pebbles. So, 36/4 = <<36/4=9>>9 friends received pebbles. #### 9
