Kelvin just received a 4% raise at work. His new pay is $11.00 per hour. What was Kelvin's hourly pay before the raise? (2 points) $7.86
$8.90
$10.58

10.58

Step-by-step explanation:

Let x be the pay before the raise

x+ 4% of x is the new pay

x + .04x = 11

1.04x = 11

Divide each side by 1.04

1.04x/1.04 = 11/1.04

x =10.57692308

Rounding to the nearest cent

x = 10.58

10.58

Step-by-step explanation:

after increasing it is now 104% or 1.04,

1.04= $11

1.00(original percentage)= 11/1.04 x 1

= $10.58

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
