Question

Arie's pet shop is selling geckos at 12 and a half percent off! if geckos were originally $20 each, what is the sale price?

Answer 1

DIscount = 121/2 % 0ff

`\begin{gathered} \text{Sales price = 12}(1)/(2)\text{ }*\text{ 20} \\ \text{ =}((25)/(2))/(100)\text{ }*20\text{ } \\ \text{ } \\ \text{ =}(25)/(200)\text{ }*20\text{ = }(500)/(200)\text{ = \$2.5} \end{gathered}`
