Question

uma camiseta que custava r$ 24 passou a custar 30 qual é a taxa percentual do aumento

Answer 1

$Ola , boa \ tarde ! \\ A \ camiseta \ custava \ 24 \passou \ a \custar\ 30 : \\ 30 - 24 = 6 \ desconto \\ Armando \ a \ regra\ tres \simples\ : \\ 24-------10 \\ 6----------x \\ Multiplicando \em\ cruz \\ 24 . x = 100 . 6 \\ 24x=600 \\ x= 600 / 24 \\ X= 25 \\ A \ taxa \percentual \do \aumento \ e \ 25 % .$

Answer 2

✅ Após resolver os cálculos, concluímos que a taxa percentual de aumento é:

                   $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf T_{\%A} = 25\:\%\:\:\:}}\end{gathered} }$

Sejam os dados:

      $\Large\begin{cases} P_{A} = Prec_{\!\!,}o\:antigo = R\ \:24,00\\N_{P} = Novo\:prec_{\!\!,}o = R\ \:30,00\\T_{\%A} = Taxa\:percentual\:de\:aumento = \:?\end{cases}$

Para calcular a taxa percentual de aumento devemos utilizar a seguinte fórmula:

$\Large\displaystyle\begin{gathered} \bf I\end{gathered}$             $\Large\displaystyle\text{ \begin{gathered} T_{\%A} = \bigg(\frac{N_{P}}{P_{A}} - 1\bigg)\cdot100\end{gathered} }$

Substituindo os valores na equação "I", temos:

              $\Large\displaystyle\begin{gathered} T_{\%A} = \bigg(\frac{30}{24}- 1\bigg)\cdot100\end{gathered}$

                         $\Large\displaystyle\begin{gathered} = (1,25 - 1)\cdot100\end{gathered}$

                         $\Large\displaystyle\begin{gathered} = 0,25\cdot100\end{gathered}$

                         $\Large\displaystyle\begin{gathered} = 25\:\%\end{gathered}$

✅ Portanto, a taxa percentual de aumento é:

               $\Large\displaystyle\begin{gathered} T_{\%A} = 25\:\%\end{gathered}$

$\LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{\:\:\:Bons \:estudos!!\:\:\:Boa\: sorte!!\:\:\:}}}\end{gathered} }$
