Anit [1.1K]

Answer:

Dinda received a 32% loss percentage.

Step-by-step explanation:

<u><em>The question in English is</em></u>

Dinda bought a phone for Rp.2,500,000.00. After 5 months, she sells it with

the price of Rp1,700,000.00. What percentage of losses did Dinda receive?

we know that

Rp.2,500,000.00 represent the 100%

so

Using a proportion

Find out what percentage represent the difference between the original value and the final value

\frac{2,500,000}{100\%}=\frac{2,500,00-1,700,000}{x}\\\\x=100(800,000)/2,500,000\\\\x=32\%

therefore

Dinda received a 32% loss percentage.

The daily profit P ​(in thousands of​ dollars) from the sale of televisions is a function of the number x of televisions sold ​(
scZoUnD [109]

Answer:

The break-even sales amounts​ is 36 or 224.

Step-by-step explanation:

Consider the provided function.

P= -5x^2 + 13x - 4

Where x is the number of televisions sold (in hundreds) and P is the profit.

We need to calculate the break-even sales amounts​.

the​ break-even sales amounts​ is the sales amounts that result in no profit or​ loss.

That means substitute P=0 and solve for x.

-5x^2 + 13x - 4=0

5x^2-13x+4=0

\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}\\x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Substitute a=4, b=-13 and c=4 in above formula.

x_{1,\:2}=\frac{-\left(-13\right)\pm \sqrt{\left(-13\right)^2-4\cdot \:5\cdot \:4}}{2\cdot \:5}

x_{1,\:2}=\frac{13\pm\sqrt{169-80}}{10}

x_{1,\:2}=\frac{13\pm\sqrt{89}}{10}

x=\frac{13+\sqrt{89}}{10},\:x=\frac{13-\sqrt{89}}{10}\\x\approx2.243, \ or\ x\approx 0.357

Therefore, the break-even sales amounts​ is 36 or 224.
