HELP. I have tried and tried and I CAN NOT solve these equations!


Numbers (The dashes are the numbers I need to solve for.)

Cost: -
Markup: -
Selling Price: $79.49
% Markup Based on Cost: 300%
% Markup Based on Selling Price: -
% Markdown: 25%
Markdown: $19.87
Sale Price: $59.62

Equations

Seling Price= Cost + Markup
% Markup Based on Cost= Markup ÷ Cost
% Markup Based on Selling Price= Markup ÷ Selling Price
% Markdown= Markdown ÷ Selling Price
Sale Price= Selling Price - Markdown

I hope y'all can figure it out... Thanks!
