Johann and two friends are to deliver 180 pieces of certified mail. His friends each deliver 41 pieces of mail. How many pieces of mail does Johann need to deliver?

Friends = 41 * 2 =

<<41*2=82>>82 Johann = 180 - 82 = <<180-82=98>>98 Johann must deliver 98 pieces of mail. #### 98 Annabelle collected a weekly allowance of $30. She spent a third of it buying junk food, then spent another $8 on sweets. Out of guilt she decides to save the rest. How much did she save? A third of $30 is $30*(1/3) = $<<30*(1/3)=10>>10 She spent $10 from $30 leaving $30-$10 = $20 She spent another $8 leaving $20-$8 = $<<20-8=12>>12 which she saved #### 12 An elevator is on the 9th floor. It goes down 7 floors, then up 3 floors, then up 8 floors. If the elevator is on the top floor, how many floors are there in the building? From the 9th floor, the elevator went down to the 9 - 7 = <<9-7=2>>2nd floor. Then went up to the 2 + 3 = <<2+3=5>>5th floor. Then, went up to the 5 + 8 = <<5+8=13>>13th floor; hence there are 13 floors in the building. #### 13 The buyers who came to Mr. Brandon's shop yesterday bought goods worth $80. If 2/5 of the total amount of sales Mr. Brandon made yesterday were credit sales, and the rest were cash sales, how much did Mr. Brandon get from cash sales? 2/5 of the total amount of sales Mr. Brandon made yesterday, which were credit purchases, were worth 2/5*$80=$<<2/5*80=32>>32 The cash sales that Mr. Brandon made yesterday was $80-$32=$<<80-32=48>>48 #### 48 Jessie invited 4 friends over to play. They made muffins for a snack and Jesse wants to divide them equally between herself and her friends. If they made 20 muffins in total, how many will each person have? There will be a total of 1 + 4 = <<1+4=5>>5 people who will share the muffins. Each of them will have 20/5 = <<20/5=4>>4 muffins. #### 4 John hits 70% of his free throws. For every foul he gets 2 shots. He gets fouled 5 times a game. How many free throws does he get if he plays in 80% of the 20 games the team plays? John plays in 20*.8=<<20*.8=16>>16 games That means he gets fouled 16*5=<<16*5=80>>80 fouls So he gets 80*2=<<80*2=160>>160 foul shots So he makes 160*.7=<<160*.7=112>>112 free throws #### 112 Ludwig works 7 days a week and he usually works half of the day during Friday, Saturday, and Sunday. If his daily salary is $10, how much does he earn every week? Ludwig earns a total of $10 x 4 = $<<10*4=40>>40 from Monday to Thursday. He earns $10/2= $<<10/2=5>>5 per day on Friday, Saturday, and Sunday. So, his total salary for Friday, Saturday, Sunday is $5 x 3 = $<<5*3=15>>15. Therefore, his total weekly salary is $40 + $15 = $<<40+15=55>>55. #### 55 Tommy goes for a run around his neighborhood and decides to calculate how many wheels he saw. All the trucks in his neighborhood have 4 wheels and all the cars in his neighborhood also have 4 wheels. If he saw 12 trucks and 13 cars, how many wheels did he see? He saw 25 total vehicles because 12 plus 13 equals <<12+13=25>>25. He saw 100 wheels because 25 times 4 equals <<25*4=100>>100. #### 100 Stephen has 110 ants in his ant farm. Half of the ants are worker ants, 20 percent of the worker ants are male. How many female worker ants are there? Worker ants:110/2=<<110/2=55>>55 ants Male worker ants:55(.20)=11 Female worker ants:55-11=<<55-11=44>>44 ants #### 44 At football tryouts, the coach wanted to see who could throw the ball the farthest. Parker threw the ball 16 yards. Grant threw the ball 25 percent farther than Parker and Kyle threw the ball 2 times farther than Grant. Compared to Parker, how much farther did Kyle throw the ball? Grant threw the ball 25% farther than Parker. If Parker threw the ball 16 yards, then Grant threw it 16*.25 = <<16*.25=4>>4 farther In total, Grant threw the ball 16+4 = <<16+4=20>>20 yards Kyle threw 2 times farther than Grant so Kyle threw the ball 2*20 = <<2*20=40>>40 yards If Kyle threw the ball for 40 yards and Parker threw for 16 then Kyle threw the ball 40-16 = <<24=24>>24 yards farther #### 24
