The sales tax on a Camera is $5.60, which is 8% of the total price. What is the price of the camera?

Answers

The amount of sales tax that is taken on the camera = $5.60
Percentage of sales tax taken on the camera = 8%
Let us assume the actual price of the camera = x dollars
Then
(8%) * x = 5.60
(8/100) * x = 5.60
2x/25 = 5.60
2x = 5.60 * 25
2x = 140
x = 140/2
= 70 dollars
So the actual price of the camera is $70. I hope the procedure is clear enough for your understanding. You can use this method for solving similar problems in future without requiring any help from outside.

A cooking club has 12 members.How many ways can they select a president and vice president from among the members?
A. 1320
B. 220
C. 132
D. 66

Answers

The correct answers are:
C) 15120
C) 132.

Explanation:
9P5 is a permutation of 9 objects taken 5 at a time; this is
9! / (9-5)! = 9!/4!
= (9*8*7*6*5*4*3*2*1)/(4*3*2*1)
= 15120.

The second question is a permutation of 12 objects taken 2 at a time; this is 12! / (12-2)! = 12!/10!
=(12*11*10*9*8*7*6*5*4*3*2*1) / (10*9*8*7*6*5*4*3*2*1)
=132

9P5 is a permutation of 9 objects taken 5 at a time; this is ⁹P₅ = 15120. So, the correct option is C.

A permutation of 12 objects taken 2 at a time; this is 132 ways can they select a president and vice president from among the members. So, the correct option is C.

Given:

9P5 is a permutation of 9 objects taken 5 at a time; this is

9! / (9-5)! = 9!/4!

= (9*8*7*6*5*4*3*2*1)/(4*3*2*1)

= 15120.

A permutation of 12 objects taken 2 at a time; this is 12! / (12-2)! = 12!/10!

=(12*11*10*9*8*7*6*5*4*3*2*1) / (10*9*8*7*6*5*4*3*2*1)

=132

Therefore, the cooking club has 12 members. there are 132 ways can they select a president and vice president from among the members
