After being discounted 40%, a weather radio sells for $35.97. find the original price. (round your answer to the nearest cent.)

tia_tia [17]

It is given in the question that

After being discounted 40%, a weather radio sells for $35.97.

It means the weather radio sells at a 60% of original price.

Let the original price be $x.

Therefore according to the question,

$60% \ of \ x = 35.97
\\
0.6x = 35.97
\\
x = $59.95$

Therefore the original price of the weather radio is $59.95.

Answer:

$x=25.24$

Step-by-step explanation:

To find the value of $x$ , we are solving the exponential equation $-6.2^{0.1x} =-100$ using logarithms.

Let's solve it step-by-step

Step 1. Divide both sides of the equation by -1 to get rid of the negative signs:

$-6.2^{0.1x} =-100$

$\frac{-6.2^{0.1x}}{-1} =\frac{-100}{-1}$

$6.2^{0.1x} =100$

Step 2. Take natural logarithm to bot sides of the equation:

$ln(6.2^{0.1x)}=ln(100)$

Step 3. Use the power rule for logarithms: $ln(a^{x} )=xln(a)$

For our equation: $a=6.2$ and $x=0.1x$

$ln(6.2^{0.1x)}=ln(100)$

$0.1xln(6.2)=ln(100)$

Step 4. Divide both sides of the equation by $0.1ln(6.2)$

$0.1xln(6.2)=ln(100)$

$\frac{0.1xln(6.2)}{0.1ln(6.2)} =\frac{ln(100)}{0.1ln(6.2)}$

$x=\frac{ln(100)}{0.1ln(6.2)}$

$x=25.24$

We can conclude that the value of x in our exponential equation is approximately 25.24.
