Trisha just got a job offer for an hourly job that pays 15 dollars an hour, 40 hours per week. She has been told to estimate that 20 percent of her pay will be withheld to pay taxes, unemployment insurance, and social security. Assuming Trisha works 52 weeks in a year, what is her annual "take-home" pay?

Trisha's pay before taxes is 15 dollars an hour x 40 hours per week x 52 weeks =

<<15*40*52=31200>>31,200 dollars The amount withheld is 20 percent, or 0.2 x 31,200 = <<0.2*31200=6240>>6,240 dollars Trisha's gross pay of 31,200 - 6,240 = <<31200-6240=24960>>24,960 dollars #### 24,960 John drives 1000 miles a month. He needs to get an oil change every 3000 miles. He gets 1 free oil change a year. If an oil change costs $50, how much does he pay a year? He needs to get an oil change every 3000/1000 = <<3000/1000=3>>3 months So he gets 12/3 = <<12/3=4>>4 oil changes a year That means he pays for 4-1 = <<4-1=3>>3 oil changes a year So he pays 3*$50 = $<<3*50=150>>150 a year #### 150 Elizabeth has 10 reusable water bottles. She loses 2 water bottles at school. Then someone steals 1 of her water bottles at dance practice. To avoid any future theft of her water bottles, Elizabeth places 3 stickers on each of her remaining bottles. How many stickers does Elizabeth use in total on her water bottles? Elizabeth has 10 - 2 - 1 = <<10-2-1=7>>7 water bottles Elizabeth uses 7 * 3 = <<7*3=21>>21 stickers #### 21 Allie's making guacamole for a party. Each batch requires 4 avocados and serves about 6 people. If 42 people are going to be at the party including her, how many avocados does she need? Each batch serves 6 people, and there are 42 people coming to the party, so she needs to make 42 / 6 = <<42/6=7>>7 batches. Each batch requires 4 avocados, so she will need 4 * 7 = <<4*7=28>>28 avocados. #### 28 A group of nine turtles sat on a log. Two less than three times the original number of turtles climbed onto the log with the original group, creating an even larger group on the log. Suddenly, half of the large group of turtles were frightened by a sound and jumped off of the log and ran away. How many turtles remained on the log? Two less than three times the original number of turtles is (9*3)-2=<<9*3-2=25>>25. Thus, The original 9 were joined by 25 more, for a total of 25+9=<<9+25=34>>34 turtles. But half of the 34 turtles scurried away, leaving half remaining, or 34/2=<<34/2=17>>17 brave turtles #### 17 Adam has just bought some new books so he has decided to clean up his bookcase. After he adds his new books to his bookshelf he realizes that he has bought enough books to finish completely filling his bookcase with 2 books left over. Before his shopping trip, Adam had 56 books in his bookcase. If his bookcase has 4 shelves and averages 20 books per shelf, how many books did Adam buy on his shopping trip? Adam’s bookshelf has 4 shelves that fit 20 books each, which is 4 * 20=<<4*20=80>>80 books in total to fill the bookshelf Adam ended the day with a full bookcase of 80 books in the bookcase and 2 books left over, 80 + 2= <<80+2=82>>82 books total. If Adam started the day with 56 books and ended the day with 82 books then Adam bought 82 - 56= <<82-56=26>>26 books bought on his shopping trip. #### 26 Mr. and Mrs. McPherson have to renew their rent by the end of the year. They agreed that Mrs. McPherson would raise 30% of the money. If their rent is $1200 per year, how much does Mr. McPherson need to raise to complete the rent? 30% of $1200 is (30/100)*$1200 = $<<(30/100)*1200=360>>360 Mrs. McPherson will pay $360 leaving $1200-$360 = $<<1200-360=840>>840 which Mr. McPherson will have to raise #### 840 James has a room that is 13 feet by 18 feet.

He increases the length to 13+2=<<13+2=15>>15 feet He increases the width to 18+2=<<18+2=20>>20 feet So the rooms are 15*20=<<15*20=300>>300 square feet So he has 1+3=<<1+3=4>>4 rooms of this size So he has 4*300=<<4*300=1200>>1200 square feet of rooms this size He also has one room of size 300*2=<<300*2=600>>600 square feet So he has 1200+600=<<1200+600=1800>>1800 square feet of rooms #### 1800 Frank went to a shop to buy some food for his breakfast. He bought 10 buns for $0.1 each, two bottles of milk, for $2 each, and a carton of eggs, which was three times more expensive than one bottle of milk. How much did Frank pay for his breakfast shopping? For the buns, Frank paid 10 * 0.1 = $<<10*0.1=1>>1. He bought two bottles of milk, for $2 each, so he paid for them 2 * 2 = $<<2*2=4>>4. One carton of eggs was three times more expensive than one bottle of milk, so it cost 3 * 2 = $<<3*2=6>>6. So for all his shopping Frank had to pay 1 + 4 + 6 = $<<1+4+6=11>>11. #### 11 Juliet is 3 years older than her sister Maggie but 2 years younger than her elder brother Ralph. If Juliet is 10 years old, what is the sum of Maggie's and Ralph's ages? Maggie is 3 years younger than Juliet who is 10 years so she is 10-3 = <<10-3=7>>7 years old Ralph is 2 years older than Maggie so he is 10+2 = 12 years old The sum of Maggie's and Ralph's ages is 7+12 = <<7+12=19>>19 years #### 19
