Question

A
count went up from 450 to 600. What was the approximate percent increase

Answer 1

if 450 is the 100%, 600 - 450 = 150, thus, what is 150 in percentage off of 450?


`\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 450&100\\ 150&x \end{array}\implies \cfrac{450}{150}=\cfrac{100}{x}`

solve for "x".
