Question

o valor do salário será majorado de R$ 1.039,00 para R$ 1.045,00. qual a taxa percentual de aumento?

Answer 1

Resposta:  0,58%

Explicação passo-a-passo:

i=1045-1039*100/1039

i=6*100/1039

i=0,58

Answer 2

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

               $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf T_{\%A} = 0,58\,\%\:\:\:}}\end{gathered} }$

Sejam os dados:

     $\Large\begin{cases} P_{A} = Prec_{\!\!,}o\:antigo = R\ \:1039,00\\N_{P} = Novo\:prec_{\!\!,}o = R\ \:1045,00\\T_{A\%} = Taxa\:de\:aumento\end{cases}$

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

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

Substituindo os dados na equação "I", temos:

              $\Large\displaystyle\begin{gathered} T_{A\%} = \bigg(\frac{1045}{1039}-1\bigg)\cdot100\end{gathered}$

                        $\Large\displaystyle\begin{gathered} = (1,0058- 1)\cdot100\end{gathered}$

                        $\Large\displaystyle\begin{gathered} = 0,0058\cdot100\end{gathered}$

                        $\Large\displaystyle\begin{gathered} = 0,58\,\%\end{gathered}$

✅ Portanto, a taxa percentual de aumento foi:

              $\Large\displaystyle\begin{gathered} T_{\%A} = 0,58\,\%\end{gathered}$

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