she saved $3, and we know the discount is 15%, so her savings is that 15%, thus we know 15% of that purchase is 3.
let's say the full price is x, and therefore the 100%, if we know 3 is the 15%, what is x?
![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 3&15\\ x&100 \end{array}\implies \cfrac{3}{x}=\cfrac{15}{100}\implies \cfrac{3\cdot 100}{15}=x\implies 20=x](https://tex.z-dn.net/?f=%20%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%203%2615%5C%5C%20x%26100%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B3%7D%7Bx%7D%3D%5Ccfrac%7B15%7D%7B100%7D%5Cimplies%20%5Ccfrac%7B3%5Ccdot%20100%7D%7B15%7D%3Dx%5Cimplies%2020%3Dx%20)
