MHB Get 25% Off - Save on E-Commerce Prices

[LorraineP]

Hello,

It's been 40 years since I've sat in a math class. And although I remember a lot, if you don't use it, you tend to lose it!
So, I have an e-commerce store and I want to set my prices as "on sale", trying a permanent sale technique, 25% off.

So here's what I thought would work:

• Desired display price = $39.95
• Entered in calculator 39.95 + 25% = $49.9375
• Entered price online as $49.94
• Set Sale to 25% off
• Price ends up as $37.46

Whereas I wanted price to end up as $39.95

What am I doing wrong? Is there a formula I can follow?

Thank you for any and all help in advance :)

let P = online price, S = sale price of 39.95

P - (25% discount of P) = S

P - 0.25P = S

P(1 - 0.25) = S

P(0.75) = S

P = S/0.75 = 39.95/0.75 = 53.27
