Well, if she sells $12,500 worth of furnitture, then she has made 15% of this money. Tell me what is 15% of 12,500?

OpenStudy (anonymous):

1.875

OpenStudy (solomonzelman):

yes, 15% of 12,500 is 1,875!

OpenStudy (anonymous):

yay

OpenStudy (solomonzelman):

You know that she needs to make $5000. And we know that she sold 12,500 worth of furniture, and being that she makes 15% commissions from furniture, we know she has made 15% of 12,500 - OR, she made 1,857 off furniture. So, if she needs to make 5,000, and has already made 1,875, then she needs 5000-1875=3125 dollars left, right?

OpenStudy (solomonzelman):

We also know that she makes 10% commissions off rugs. However, we don't know how many rugs she is going to sell.

OpenStudy (anonymous):

ok

OpenStudy (solomonzelman):

Let "x" be the price of all runs that she is going to sell.

OpenStudy (anonymous):

what i need to do next

OpenStudy (solomonzelman):

We need to have "x" as large as that 10% of x is equal to 3,125...

OpenStudy (solomonzelman):

because we need these 3,125 dollars, to make $5000 overall.

OpenStudy (solomonzelman):

So, the question you need to answer is, 10% of what number (x) is equivalent to 3125?

OpenStudy (anonymous):

is it c?

OpenStudy (solomonzelman):

Yes, fabulous!

OpenStudy (anonymous):

thank you!:)

OpenStudy (solomonzelman):

If, 10% of x is 3125, then we know that x is 10 times greater. (with no need to go into percentage calculations, which even they are simple enough)
