What is the approximate solution to this equation?

Nookie1986 [14]

Answer:

C. x ≈ 0.28

Step-by-step explanation:

A graphing calculator solution is attached. It shows ...

x ≈ 0.28

You can divide both sides of the given equation by 5, then take natural logs and divide by 5 again.

5e^(5x) = 20 . . . . . . given

e^(5x) = 4 . . . . . . . . divide by 5

5x = ln(4) . . . . . . . . take natural logs

x = ln(4)/5 . . . . . . . divide by 5

x ≈ 0.277259 ≈ 0.28

Hisako sells dolls at her doll store. If she sells a doll for $35, and there is 6% sales tax, what is the tax amount a customer

Sloan [31]

Given:

The price of a doll = $35

Sales tax = 6%

To find:

The tax amount that a customer will pay on one doll.

Solution:

The price of doll is $35 and the sales tax is 6%, so the tax amount on a doll is 6% of 35.

$\text{Tax amount}=35\times \dfrac{6}{100}$

$\text{Tax amount}=\dfrac{210}{100}$

$\text{Tax amount}=\dfrac{21}{10}$

$\text{Tax amount}=2.1$

Therefore, the tax amount that a customer will pay on one doll is $2.1.
