John's neighbor tells him to walk his dog for 1 hour each day for a total of $10. He does this for April, save for the 4 Sundays in April. He later spent $50 on books and gave his sister Kaylee the same amount. How much money did John have left?

April has 30 days, so if he didn't walk the dog on Sundays, he worked for a total of 30 days - 4 days =

<<30-4=26>>26 days. If each day he earned $10, he ends up with 26 days * $10/day = $<<26*10=260>>260 . After buying books and giving his sister $50, he ends up with $260 - $50 - $50 = $<<260-50-50=160>>160 #### 160 Holly gets 26 paychecks per year. If she puts $100.00 from every paycheck into her 401K, her company will match that contribution by 6%. How much money has she and her company contributed to her 401k after 1 year? She puts $100.00 into her 401k from every paycheck and she gets 26 paychecks so that’s 100*26 = $<<100*26=2600.00>>2,600.00 Her company matches her $100.00 by 6% so they contribute 100*.06 = $<<100*.06=6.00>>6.00 every paycheck Over a year, the company contributes $6.00 to her 401k with every paycheck so they contribute 6*26 = $<<6*26=156.00>>156.00 Holly puts $2,600.00 into her 401k annually and her company contributes $156.00 annually so she has 2600+156 = $<<2600+156=2756>>2,756 in her 401k #### 2756 Linda is painting her bedroom. Her bedroom has 4 walls, with the room being 20 feet wide by 20 feet long by 8 feet tall. One wall has a 3-foot by 7-foot doorway. A second wall has a 6-foot by 4-foot window. A third wall has a 5-foot by 7-foot doorway to a walk-in-closet. And the fourth wall is completely solid. What is the total area of wall space that Linda will have to paint? The solid wall is 8 ft. * 20 ft. = <<8*20=160>>160 sq. ft. The doorway is 3 ft. * 7 ft. = <<3*7=21>>21 sq. ft. The window is 6 ft. * 4 ft. = <<6*4=24>>24 sq. ft. The closet door is 5 ft. * 7 ft. = <<5*7=35>>35 sq. ft. The total area of the doors and windows is 21 sq. ft + 24 sq. ft. + 35 sq. ft. = <<21+24+35=80>>80 sq. ft. The solid wall is 160 sq. ft., so before the areas of the doors and window are taken into account, the total wall area is 4 * 160 sq. ft. = <<4*160=640>>640 sq. ft. Taking into account the doors and window, the total wall area Linda will have to paint is 640 sq. ft. - 80 sq. ft. = <<640-80=560>>560 sq. ft. #### 560 Mr. Llesis had 50 kilograms of rice. He kept 7/10 of it in storage and gave the rest to Mr. Everest. How many kilograms of rice did Mr. Llesis keep than Mr. Everest? Mr. Llesis kept 50 x 7/10 = <<50*7/10=35>>35 kilograms of rice. So, he gave 50 - 35 = <<50-35=15>>15 kilograms of rice to Mr. Everest. Therefore, Mr. Llesis kept 35 - 15 = <<35-15=20>>20 kilograms more than Mr. Everest. #### 20 Elmer has a pond that initially contained 2400 pollywogs, but these pollywogs matured into toads and left the pond at a constant rate of 50 pollywogs per day. In addition, Elmer has a son named Melvin, who loves to catch pollywogs, remove them from the pond, and release them into a nearby stream. For the first 20 days, Melvin caught 10 pollywogs per day and released them into the stream. How many days did it take for all of the pollywogs to disappear from the pond? For the first 20 days, the combined rate of disappearance of pollywogs from the pond is 50+10=<<50+10=60>>60 pollywogs per day. During these first 20 days, the total number of pollywogs removed was 60*20=<<60*20=1200>>1200 pollywogs. This means after 20 days there were 2400-1200=<<2400-1200=1200>>1200 pollywogs left in the pond. At a disappearance rate of rate 50 pollywogs per day, it will take an additional 1200/50=<<1200/50=24>>24 days for the rest of the pollywogs to disappear from the pond. Thus, overall, it will take 20+24=<<20+24=44>>44 days for all of the pollywogs to disappear from the pond. #### 44 If the number of dogs in the neighborhood was originally half the number of cats in the neighborhood before twenty new dogs were born, and now there are twice as many dogs as cats, how many cats were in the neighborhood, to begin with, if there are 20 cats now? Now there are twice as many dogs as cats, and if the number of cats is 20, there are 2*20=<<2*20=40>>40 dogs. Before twenty new ones were born, the number of dogs in the neighborhood originally was 40-20=<<40-20=20>>20 If the number of dogs in the neighborhood was originally half the number of cats in the neighborhood, there were 20*2=<<20*2=40>>40 cats in the neighborhood. #### 40 Roxanne bought 2 cups of lemonade for $2 each and 2 sandwiches for $2.50 each. How much change must she get from a $20 bill? Two cups of lemonade amount to $2 x 2 = $<<2*2=4>>4. Two sandwiches amount to $2.50 x 2 = $<<2.5*2=5>>5. So, the total amount that Roxanne had to pay was $4 + $5 = $<<4+5=9>>9. Thus, her change must be $20 - $9 = $<<20-9=11>>11. #### 11 Mark just got a new puppy that cost $10. He also bought enough food for 3 weeks. He knows the puppy eats 1/3 cup of food a day. A bag of food with 3.5 cups costs $2. How much did all of this cost him? He needs food for 21 days because 3 x 7 = <<3*7=21>>21 The puppy will eat 7 cups of food because 21 x (1/3) = <<21*(1/3)=7>>7 He needs 2 bags of food because 7 / 3.5 = <<7/3.5=2>>2 The food will cost him $4 because 2 x 2 = <<2*2=4>>4 It will cost $14 in total because 10 + 4 = <<10+4=14>>14 #### 14 Grant has four times as many vacations as Kelvin has classes. If Kelvin has 90 classes, how many vacations and classes do Grant and Kelvin have altogether? Grant has 4*90 = <<4*90=360>>360 vacations. In total, they have 360 + 90 = <<360+90=450>>450 vacations and classes. #### 450 Enid and Aaron are knitting clothes for their store. Aaron makes 10 scarves and 5 sweaters, and Enid makes 8 sweaters. If a scarf uses 3 balls of wool and a sweater uses 4 balls of wool, how many balls of wool did Enid and Aaron use in total? Aaron used 10 scarves * 3 balls of wool = <<10*3=30>>30 balls of wool to make his scarves. He also used 5 sweaters * 4 balls of wool = <<5*4=20>>20 balls of wool to make his sweaters. Enid used 8 sweaters * 4 balls of wool = <<8*4=32>>32 balls of wool to make her sweaters. So in total, Aaron used 30 + 20 + 32 = <<30+20+32=82>>82 balls of wool. #### 82
