Can you help me with this question please

Given:

Amount = £399

Ratio of amount gets Ann to Bill = 2 : 9

Chloe and Dave get 2.5 times the amount Ann gets.

To find:

The amount of money that Bill gets.

Solution:

Let Ann, Bill, Chloe and Dave gets 2x, 9x, 2.5 × 2x and 2.5 × 2x.

Divide by 21 on both sides.

x = 19

Amount that Bill gets = 9x

                                   = 9 × 19

                                   = 171

The amount of money that Bill gets £171.

step-by-step explanation:

use a calculator!

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
