Explanation
The sequence is formed by adding consecutive odd numbers to the previous number. Starting with 2, we add 1 to get 3, then add 2 to get 5, then add 3 to get 8, and so on. In this case, we add 7 to 24 to get 31, and then add 1 to get 32. Therefore, the next number in the sequence is 32.

Louis works 3 days per week. His car gets 30 miles to the gallon and each commute to work is 10 miles each way. If gas is $2.89 per gallon, how much will Louis spend on gas in two weeks? ( pencil, paper ok, but NO calculator)
- A.
  
  $11.56
- B.
  
  $13.79
- C.
  
  $17.54
- D.
  
  $23.89
- E.
  
  $19.95
Correct Answer
A. $11.56

Explanation
Louis works 3 days per week, so in two weeks, he will work 3 x 2 = 6 days. Each day, he commutes 10 miles each way, so his total daily commute is 10 x 2 = 20 miles. In two weeks, his total commute will be 20 x 6 = 120 miles. His car gets 30 miles to the gallon, so he will need 120 / 30 = 4 gallons of gas for his commute in two weeks. Gas is $2.89 per gallon, so he will spend 4 x $2.89 = $11.56 on gas in two weeks.

There are 3 types of marbles in a bowl. Red ones, yellow ones, and blue ones. There are 20 red marbles and 12 yellow marbles. There are three times as many blue marbles as there are red marbles. How many marbles are in the bowl? ( must do the problem in your head)
- A.
  
  76 marbles
- B.
  
  68 marbles
- C.
  
  92 marbles
- D.
  
  80 marbles
- E.
  
  86 marbles
Correct Answer
C. 92 marbles

Explanation
If there are 20 red marbles and 12 yellow marbles, then the total number of red and yellow marbles is 20 + 12 = 32 marbles. Now, since there are three times as many blue marbles as there are red marbles, there would be 3 * 20 = 60 blue marbles. Therefore, the total number of marbles in the bowl would be 32 (red and yellow marbles) + 60 (blue marbles) = 92 marbles.

Joe is having a cookout. He has bought 5 lbs of hamburger for $7.99 and 3 packages of hotdogs for $1.99 each. If Joe paid for all of this with a $20 bill, how much money does he have left over? ( do the problem in your head)

  $4.98
- E.
  
  $ 6.98
Correct Answer
B. $6.04

Explanation
Joe spent a total of $7.99 on hamburger and $1.99 x 3 = $5.97 on hotdogs. Therefore, Joe spent a total of $7.99 + $5.97 = $13.96. Joe paid with a $20 bill, so he has $20 - $13.96 = $6.04 left over.

Jack caught 14 fishes on Saturday and twice as much fish on Sunday. When he went fishing on Monday, he caught 1/2 of the fish he caught on Saturday and Sunday combined. How many total fish did he catch all 3 days? ( do the problem in your head)
- A.
  
  63 fish
- B.
  
  57 fish
- C.
  
  71 fish
- D.
  
  59 fish
- E.
  
  68 fish
Correct Answer
A. 63 fish

Explanation
Jack caught 14 fish on Saturday and twice as much fish on Sunday, which means he caught 14 x 2 = 28 fish on Sunday. Therefore, the total number of fish he caught on Saturday and Sunday combined is 14 + 28 = 42 fish. On Monday, he caught 1/2 of the fish he caught on Saturday and Sunday combined, which is 1/2 x 42 = 21 fish. So, the total number of fish he caught all three days is 14 + 28 + 21 = 63 fish.
