Answer 1

@saifoo.khan help...? :)

Answer 2

So 6.54

Answer 3

i think i did something wrong.

Answer 4

Ah, stupid me!

Answer 5

What'd u do wrong

Answer 6

Ok, so she earns $200.
And whatever she earns after it, is her commission.

Answer 7

Therefore:

218 - 200 = $18

Now $18 is her COMMISSION!!

Which is only 3% of the TOTAL SALES!

Answer 8

So it's .54 @saifoo.khan ?

Answer 9

Sorry i was away.

Answer 10

So, 18 is the 3 of the TOTAL which is 100%!

Answer 11

18 is 3%
x is 100%

Now cross multiply and solve for x.

Answer 12

What are the fractions to cross multiply? @saifoo.khan I'm confused

Answer 13

Yes.

Answer 14

it's called the ratio method.

18 : 3
x : 100

Answer 15

So 18 over x and 3 over 100?

Answer 16

Yes, you can do that way as well

Answer 17

So the answer is 600....?

Answer 18

Or 60? @saifoo.khan
