Earl has $90; Fred has $48; Greg has $36. Earl owes Fred $28. Fred owes Greg $32. Greg owes Earl $40. When all debts are paid, how much will Greg and Earl have together in dollars?

Earl will have $90 - $28 = $

<<90-28=62>>62 after paying off his debt to Fred. Fred will have $48 + $28 = $<<48+28=76>>76 after being paid by Earl. But then Fred will have $76 - $32 = $<<76-32=44>>44 after paying Greg. Greg will have $36 + $32 = $<<36+32=68>>68 after Fred paid him. Then, Greg will have $68 - $40 = $<<68-40=28>>28 after paying off his debt to Earl. Then, Earl will then have $62 + $40 = $<<62+40=102>>102. So together, Greg and Earl will have $28 + $102 = $<<28+102=130>>130. #### 130 A dental office gives away 2 toothbrushes to every patient who visits. His 8 hour days are packed and each visit takes .5 hours. How many toothbrushes does he give in a 5 day work week? Each day he does 8/.5=<<8/.5=16>>16 visits So he does 16*5=<<16*5=80>>80 visits a week That means he gives away 80*2=<<80*2=160>>160 toothbrushes a week #### 160 5 squirrels collected 575 acorns. If each squirrel needs 130 acorns to get through the winter, how many more acorns does each squirrel need to collect? Each squirrel now has 575/5 = <<575/5=115>>115 acorns. Each squirrel still needs to collect another 130 - 115 = <<130-115=15>>15 acorns. #### 15 In a class of 25 students, students were asked if they like French fries, burgers, or neither. 15 students said they like French fries and 10 said they like burgers, with these statistics including the responses of 6 students who said they like both French fries and burgers. How many students do not like either food? There are 15 - 6 = <<15-6=9>>9 students who like French fries only. There are 10 - 6 = <<10-6=4>>4 students who like burgers only. So, 9 + 4 + 6 = <<9+4+6=19>>19 students like either French fries, burgers, or both. Hence, 25 - 19 = <<25-19=6>>6 students do not like either fries or burgers. #### 6 A coffee shop brews 10 coffee cups per hour on a weekday and 120 coffee cups in total over the weekend. If the coffee shop is open 5 hours a day every single day, how many coffee cups are brewed in 1 week? On a weekday, the shop produces 10 coffee cups per hour * 5 hours per weekday = <<10*5=50>>50 coffee cups. The coffee shop therefore brewed 50 coffee cups per day * 5 weekdays in a week = <<50*5=250>>250 coffee cups. So in total, the coffee shop brewed a total of 250 weekday coffee cups + 120 weekend coffee cups = <<250+120=370>>370 coffee cups in 1 week. #### 370 Jenny has a tummy ache. Her brother Mike says that it is because Jenny ate 5 more than thrice the number of chocolate squares that he ate. If Mike ate 20 chocolate squares, how many did Jenny eat? Thrice the number of chocolate squares that Mike ate is 20 squares * 3 = <<20*3=60>>60 squares. Jenny therefore ate 60 squares + 5 squares = <<60+5=65>>65 chocolate squares #### 65 Jake is retrieving the notes on a communal board, putting all of the red notes in the complaints bin and all of the blue notes in the compliments bin. The red notes were in 5 rows with 6 notes in each row. There are 2 blue notes under each of the red notes, as well as another 10 blue notes scattered at the bottom of the board. How many notes in total are put into the complaints and compliments bins? There are a total of 5 rows of red notes * 6 notes per row = <<5*6=30>>30 red notes on the board. There are 2 blue notes per red notes * 30 red notes = 60 blue notes under the red notes. With the other blue notes at the bottom of the board, there are a total of 60 + 10 = <<60+10=70>>70 blue notes. So in total, there are 30 red notes + 70 blue notes = <<30+70=100>>100 notes in total. #### 100 Bob runs 6 miles per hour. His friend Jim runs at 9 miles per hour. If Bob has a 1 mile head-start, how many minutes will it take before Jim catches him? Bob runs .1 miles per minute because 6 / 60 = <<6/60=.1>>.1 Jim run at .15 miles per minute 9 / 60 = <<9/60=.15>>.15 We know that .1(Number of Minutes) + 1 = .15(Number of Minutes) Therefore 1 = .05(Number of minutes) Therefore (Number of minutes) = 20 because 1 / .05 = <<1/.05=20>>20 #### 20 A flagpole is 12 feet tall. It breaks, folding over in half, such that what was the tip of the flagpole is now dangling two feet above the ground. How far from the base, in feet, did the flagpole break? The break occurred (12-2)/2=5 feet from the top. Then it was 12-5=<<12-5=7>>7 feet from the base. #### 7 Paige bought some new stickers and wanted to share them with 3 of her friends. She decided to share a sheet of 100 space stickers and a sheet of 50 cat stickers equally among her 3 friends. How many stickers will she have left? Paige has 100 space stickers that she is dividing among 3 friends, so 100 stickers / 3 friends = 33 stickers for each friend, with 1 remaining. She also has 50 cat stickers that she is diving among 3 friends, so 50 stickers / 3 friends = 16 stickers for each friend, with 2 remaining. So Paige will have 1 remaining space sticker + 2 remaining cat stickers = <<1+2=3>>3 stickers left. #### 3
