![\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 25&100\\ 7&x \end{array}\implies \cfrac{25}{7}=\cfrac{100}{x}\implies 25x=700\implies x=\cfrac{700}{25}\implies x=28](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccll%7D%20amount%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%2025%26100%5C%5C%207%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B25%7D%7B7%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%2025x%3D700%5Cimplies%20x%3D%5Ccfrac%7B700%7D%7B25%7D%5Cimplies%20x%3D28)
