Dawn earns 48,000 a year in 12 equal monthly payments. Each month, she saves 10% of her salary. How much does she save each month?
Dawn earns $4,000 a month because 48,000 / 12 =
<<48000/12=4000>>4000 She saves $400 a month because 4,000 x .1 = <<4000*.1=400>>400 #### 400 There are 100 people in a theater. If 19 of these people have blue eyes, half of them have brown eyes, a quarter have black eyes, and the rest have green eyes, how many of them have green eyes? 100/2 = <<100/2=50>>50 people in the theater have brown eyes. 100/4 = <<100/4=25>>25 people in the theater have black eyes. There are 50+25+19 = <<50+25+19=94>>94 people in the theater with either brown, black, or blue eyes. There are 100-94 = <<100-94=6>>6 people in the theater with green eyes. #### 6 On Monday, a restaurant sells forty dinners. On Tuesday, it sells 40 more dinners than it did Monday. On Wednesday, it sells half the amount of dinners it sold on Tuesday. On Thursday they changed their recipe, and then sold 3 more dinners than they did on Wednesday. How many dinners were sold in those 4 days? On Tuesday the restaurant sells 40+40 = <<40+40=80>>80 dinners. On Wednesday the restaurant sells 80/2 = <<80/2=40>>40 dinners. On Thursday the restaurant sells 40+3 = <<40+3=43>>43 dinners. In those 4 days, the restaurant sells a total of 40+80+40+43 = <<40+80+40+43=203>>203 dinners. #### 203 Laura needs to buy window treatments for 3 windows in her house. She will need to buy a set of sheers and a set of drapes for each window. The sheers cost $40.00 a pair and the drapes cost $60.00 a pair. How much will the window treatments cost? She needs a set of sheers that cost $40.00 and a set of drapes that cost $60.00 per window so that will cost her 40+60 = $<<40+60=100.00>>100.00 She had 3 windows she needs window treatments for they cost her $100.00 each so 3*100 = $<<3*100=300.00>>300.00 #### 300 Mindy has 7 less than 9 times as many emails waiting for her as phone messages. If she has a total of 93 emails and phone messages combined, how many emails does she have? Let e be the number of emails Mindy has and m be the number of phone messages? We know that e + m = 93 and e = 9m - 7. Substituting the second equation into the first equation, we get 9m - 7 + m = 93 Combining like terms, we get 10m - 7 = 93 Adding 7 to both sides of the equation, we get 10m = 100 Dividing both sides by 10, we get m = <<10=10>>10 Substituting this value back into the equation e = 9m - 7, we get e = 9 * 10 - 7 = 90 - 7 = 83 #### 83 Zayne sells bracelets for $5 each and two for $8. If he started with 30 bracelets and made $60 from selling bracelets for $5 each, how much in total did he make from selling his bracelets? If the bracelets he sold at $5 made $60, he sold $60/$5 = <<60/5=12>>12 bracelets. If the total number of $5 bracelets was 12, then the total number of bracelets he sold was 30-12 =18 If he was selling a pair of bracelets at $8, he sold 18/2 = 9 pairs. The total amount of money he made from selling the nine pairs is $8 * 9 = $<<8*9=72>>72 His total earnings from selling all of his bracelets are $72 + $60 = $<<72+60=132>>132 #### 132 Mrs. Crocker made 11 pieces of fried chicken for Lyndee and her friends. If Lyndee only ate one piece but each of her friends got to eat 2 pieces, how many friends did Lyndee have over? After Lyndee ate, there were 11 - 1 = <<11-1=10>>10 pieces of chicken left. Lyndee had 10/2 = <<10/2=5>>5 friends over. #### 5 Jeff orders a Halloween costume. He has to put in a 10% deposit and then pay the rest when he picks it up. The costume is 40% more expensive than last year's costume, which cost $250. How much did he pay when picking it up, in dollars? It cost 250*.4=$<<250*.4=100>>100 more than his old costume So it cost 250+100=$<<250+100=350>>350 He left a 350*.1=$<<350*.1=35>>35 deposit So he had to pay 350-35=$<<350-35=315>>315 #### 315 Peggy has 6 dolls. Her grandmother gives Peggy her own collection of 30 dolls. Over the year, Peggy receives half that amount of dolls between her birthday and Christmas. How many dolls does Peggy now have? Peggy has 6 dolls and her grandmother gave her 30 so that’s 6+30 = <<6+30=36>>36 dolls Over the holidays, Peggy is gifted half the number of dolls her grandmother gave her, so she receives 30/2 = <<30/2=15>>15 more dolls Peggy had 36 dolls and received another 15 for a total of 36+15 = <<36+15=51>>51 dolls #### 51 Nick is asking all his co-workers to chip in for a birthday gift for Sandra that costs $100. The boss agrees to contribute $15, and Todd volunteers to contribute twice as much since he always has to one-up everyone. If the remaining 5 employees (counting Nick) each pay an equal amount, how much do they each pay? First find Todd's contribution by doubling the boss's contribution: $15 * 2 = $<<15*2=30>>30 Now subtract Todd and the boss's contributions to find out how much still needs to be paid: $100 - $30 - $15 = $<<100-30-15=55>>55 Now divide the remaining cost by the number of employees to find the cost per employee: $55 / 5 employees = $<<55/5=11>>11/employee #### 11
