Jeff spends three times as many hours on the weekend catching up with his Facebook pals as he does working. Monday through Friday, however, he spends four times as many hours working as he does catching up. If he spends 3 hours every day catching up, how many hours does he spend working in an entire week?

How many hours does Jeff work on the weekend? ** On the weekend, Jeff works 3 / 3 =

<<3/3=1>>1 hour each day. How many hours does Jeff spend working on the weekdays? ** On the weekdays, he spends 4 * 3 = <<4*3=12>>12 hours working each day. How many hours does Jeff spend working in an entire week? ** Thus, he spends 2 * 1 + 5 * 12 = <<2*1+5*12=62>>62 hours working each week. #### 62 John worked 8 hours a day every day from the 3rd to the 8th, including the 3rd and not including the 8th. How many hours did he work?

A rectangular table seats 10 pupils while a square table seats 4 pupils. How many square tables are needed so that 90 pupils can read at the same time? How many pupils do the rectangular tables seat? ** The rectangular tables seat 7*10=<<7*10=70>>70 pupils. How many pupils do the square tables seat? ** The square tables will seat 90-70=<<90-70=20>>20 pupils. How many square tables are needed? ** The library needs 20/4=<<20/4=5>>5 square tables. #### 5 Makenna is selling candy for her Softball Team. The box contains 25 milk chocolate bars, 25 dark chocolate bars, 25 milk chocolate with almond bars, and 25 white chocolate bars. What is the percentage of each type of chocolate bar? How many chocolate bars are there? ** Since there are four types of chocolate bars and each type has 25 bars, the total number of chocolate bars is 25*4=<<25*4=100>>100. What is the percentage of each type of chocolate bar? ** Since there is a total of 100 chocolate bars and four types of chocolate, we divide 100/4=<<100/4=25>>25%. #### 25 To make a cherry pie, Veronica needs 3 pounds of pitted cherries. There are 80 single cherries in one pound of cherries. It takes 10 minutes to pit 20 cherries. How many hours will it take Veronica to pit all the cherries? How many cherries does Veronica need? ** There are 80 cherries in a pound and she needs 3 pounds to make a pie so she needs 80*3 = <<80*3=240>>240 cherries How many units of cherries does Veronica have? ** It takes her 10 minutes to pit a unit of 20 cherries. She has 240/20 = <<240/20=12>>12 units of cherries to pit How many minutes will it take Veronica to pit all the cherries? ** It takes 10 minutes to pit a unit of cherries and she has 12 units so it will take her 10*12 = <<10*12=120>>120 minutes How many hours will it take Veronica to pit all the cherries? ** 60 minutes are in 1 hour and it takes her 120 minutes so that’s 120/60 = <<120/60=2>>2 hours #### 2 John uses 5 liters of fuel per km to travel. How many liters of fuel should John plan to use if he plans to travel on two trips of 30 km and 20 km? How many liters of fuel will John use on the first trip? ** The first trip will use 30*5=<<30*5=150>>150 liters of fuel. How many liters of fuel will John use on the second trip? ** The second trip will use 20*5=<<20*5=100>>100 liters of fuel. How many liters of fuel will John use in total? ** The total liters of fuel are 150+100=<<150+100=250>>250 liters. #### 250 A big snowstorm caused a large amount of snow to fall onto Grandpa's farm, and the wind caused the snow to pile up into a drift. But on the second day, it warmed up enough that half of the snowdrift melted. The third day, it snowed again, adding another 6 inches of snow onto the snowdrift. On the fourth day, another 18 inches of snow fell onto the snowdrift. If the snowdrift was 34 inches deep at the end of the fourth day, how deep in inches was the drift at the end of the first day? How many inches did the third and fourth day contribute to the depth of the snowdrift? ** The third and fourth day contributed 6+18=<<6+18=24>>24 inches to the depth of the snowdrift. How deep was the snowdrekt after half was melted on the second day? ** Therefore, the size of the snowdrift after half was melted on the second day, but before the snowfall on the third and fourth day, was 34-24=<<34-24=10>>10 inches. How deep was the original drift created on day 1? ** If the size of the drift on the second day, after half of the snow had melted, was 10 inches, then the depth of the original drift created on day 1 was 2*10=20 inches deep. #### 20 Ed and Jacob already had 2 shells in their shell collection. Then they went to the beach to collect even more. Ed found 7 limpet shells, 2 oyster shells, and 4 conch shells. Jacob found 2 more shells than Ed did. How many shells do the pair have altogether? How many shells did Ed find? ** Ed found 7 shells + 2 shells + 4 shells = <<7+2+4=13>>13 shells at the beach. How many shells did Jacob find? ** Jacob found 13 shells + 2 shells = <<13+2=15>>15 shells at the beach. How many shells do Ed and Jacob have altogether? ** In total Ed and Jacob have 2 shells + 13 shells + 15 shells = <<2+13+15=30>>30 shells. #### 30 Dawn, Lydia, and Donna have a total of 200 bananas. Dawn has 40 more bananas than Lydia. If Lydia has 60 bananas, how many bananas does Donna have?

How many bananas do Dawn and Lydia have? ** The total number of bananas Dawn and Lydia have is 100+60 = <<100+60=160>>160 bananas. How many bananas does Donna have? ** Donna has 200-160 = <<200-160=40>>40 bananas. #### 40 Bianca worked for 12.5 hours last weekend.
