As a sales person, your commission is directly proportional to the dollar amount of sales you make. If your sales are $800, your commission is $112. How much

You are welcome 

If you sale by  $800  your commission is $112. 

make it fraction . 

$\frac{800}{112}$ 

now if you sale by 1400$ how much is the commission 

again make this as fraction too 

$\frac{1400}{x}$

equal the two fractions and solve for x 

$\frac{800}{112} = \frac{1400}{x}$

$x = \frac{112*1400}{800}$

$x = 196$

so the commission is 196$ 

is that helps ? 

Totally, Thanks! :)

112/800=.14 X 100=14% comm.earned on sales

14% X 1,400=$196 comm. earned on $1,400 sales.

Thank you! :)
