Question

o salario minimo num determinado periodo passou de 850 para 900 qual a taxa percentual aproximada de aumento

Answer 1

900 - 850 = 50

50$ de aumento

50 / 850 = 0,058

0,058 * 100 = 5,8

5,8% de aumento

Answer 2

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

                   $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf T_{\%A} = 5,88\:\%\:\:\:}}\end{gathered} }$

Sejam os dados:

      $\Large\begin{cases} P_{A} = Prec_{\!\!,}o\:antigo = R\ \:850,00\\N_{P} = Novo\:prec_{\!\!,}o = R\ \:900,00\\T_{\%A} = Taxa\:percentual\:de\:aumento = \:?\end{cases}$

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:

              $\Large\displaystyle\begin{gathered} T_{\%A} = \bigg(\frac{900}{850}- 1\bigg)\cdot100\end{gathered}$

                         $\Large\displaystyle\begin{gathered} = (1,0588 - 1)\cdot100\end{gathered}$

                         $\Large\displaystyle\begin{gathered} = 0,0588\cdot100\end{gathered}$

                         $\Large\displaystyle\begin{gathered} = 5,88\:\%\end{gathered}$

✅ Portanto, a taxa percentual de aumento é:

               $\Large\displaystyle\begin{gathered} T_{\%A} = 5,88\:\%\end{gathered}$

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