Question

Breanna sold 1,200 Of Clothes At The dress shop and earned a commission of $210. What is her commission percent?

Answer 1

if we take 1200 to be the 100%, then what is 210 off of it in percentage?


`\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 1200&100\\ 210&x \end{array}\implies \cfrac{1200}{210}=\cfrac{100}{x}\implies x=\cfrac{210\cdot 100}{1200}`
