Calculate the limit value of monthly electricity consumption in kWh of rates D1 and D2, at which it is worth it to change the rate (from D1 to D2 or vice versa). The energy company offers the following pricelists (very confusing for an ordinary user, especially because the electricity meter measures one number - consumption in kWh, and one always pays a monthly fix + payment for the taken quantity. Again it holds that let the pricelist be as complicated as possible, so that people understand it as little as possible and ask. ..)

Final Answer:

x =  210.34 kWh

Step-by-step explanation:

$$\begin{gathered} 2.904720+0,175605\cdot x=6.816840+0.157006\cdot x \\ 2.904720+0.175605\cdot x=6.816840+0.157006\cdot x \\ 0.018599x=3.91212 \\ x=\frac{3.91212}{0.018599}=210.34034088 \\ x=210.340341=210.34\text{kWh} \end{gathered}$$
