Throughout 55783

Mr. Novak's salary is € 550. The employer decides to raise his salary by 15% but later reduces wages throughout the company by 15%. Calculate what salary Mr. Novák will have.

Correct answer:

x =  537.63 Eur

Step-by-step explanation:

$$\begin{gathered} r_1=100\%+15\%=1+\frac{15}{100}=1.15 \\ {r}_2=100\%-15\%=1-\frac{15}{100}=0.85 \\ a=550\text{Eur} \\ b=r_2\cdot a=0.85\cdot 550=\frac{935}{2}=467.5\text{Eur} \\ x=r_1\cdot b=1.15\cdot 467.5=537.63\text{Eur} \end{gathered}$$
