Answer:

57,120

explanation:

Variations = n!/(n-r)!

n = Variations

2 - Streamers

8 - Wheel Decorations

4 - Training Wheels

3 - Bells

n= (2+8+4+3) = 17

r = number of Objects

Streamers

Wheel Deceleration

Training wheels

Bells

r = 4

Variations = 17!/(17-4)! = 17!/13! = 57,120 different combinations

Leila, Charlie, and Joe have a total of $144 in their wallets. Joe has 4 times what Leila has. Charlie has $6 more than Leila. H
ollegr [7]

Answer:

The amounts of money each has are:

Joe = $92

Charlie = $29

Leila = $23

Step-by-step explanation:

To solve this, we will convert the statements into an equation, and use that to solve for the unknowns, as follows:

total amount = $144

Let Leila's share be S

Joe's share = 4 times Leila's = 4S

Charlie's share = $6 + Leila's share = 6 + S

Joe's share + Charlie's Share + Leila's Share = $144

4S + (6 + S) + S = 144

4S + 6 + S + S = 144

4S + 2S + 6 = 144

6S + 6 = 144

6S = 144 - 6 = 138

S = 138 ÷ 6 = $23

Therefore Leila's share 'S' = $23

Joe share= 4S = 4 × 23 = $92

Charlie's share = 6 + 23 = $29
