Ilya [14]

Answer:

There are approximately 4.3 weeks in each month. How much will you take home each month after taxes?​
Marianna [84]

Answer:

So roughly c x c = b/100

5 x 5 x 100 = $2500

Step-by-step explanation:

Lets say c = 5 and b = 1

= 5c =100c/5c x b

= 20c x b

We can also show

= 20c x b =5c

c = 20c/5c x b = 5c

1/20 x 5c = 5c

b=1

One example is 20%  = 0.20 x 500 = 100c  

=  7.12c  = 7c

1= 100%

100 x 71.042  = 710.42 weekly pay. emergency tax 142 = 568

100 x 71.042 = 710.42 weekly pay, normal tax 15% 142.084 =107

710-107 = 603 a week

4.3/7 x 603/7 = 86.1428571429 x 30 = 2584.29
