Australia I need help with your skills

[John G]

Hi I need your help. I have this simple accounting problem but I got stuck.

This is the problem:

I need to set a value base price for a product to be sold an an online business,
Then Paypal will tax me 3.9% for each sale
At the end after paypal deducted me the 3.9% I have to end up with $140 dollars.

The 3.9% is a constant
The $140 is a constant, it is my final goal

I believe that the equation is

x - 3.9% = 140

but I may be wrong.

Can you help me please because I got stuck and I can’t figure out what should be my initial price.
Thank you

140/(100-3.9)*100 gives you £145.68. 3.9% of that is £5.68, leaving you with the £140 that you need.
