Question

Tessa bought stock in a restaurant for $253.00. Her stock is now worth $333.96. What is the percentage increase of the value of Tessa's stock? A.) 81% B.) 32% C.) 24% D.) 76%

Answer 1

so the difference is 333.96 - 253 namely 80.96.

now, if we take 253 to be the 100%, what is 80.96 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 253&100\\ 80.96&x \end{array}\implies \cfrac{253}{80.96}=\cfrac{100}{x}\implies 253x=8096 \\\\\\ x=\cfrac{8096}{253}\implies x=32$
