Given:
The selling price of a ratio set = 72.00
Profit percent = 8%
To find:
The cost price for the radio set.
Solution:
Let x be the cost price for the radio set.
Radio set is sold at 8% profit.
![\text{Selling price}=x+\dfrac{8}{100}x](https://tex.z-dn.net/?f=%5Ctext%7BSelling%20price%7D%3Dx%2B%5Cdfrac%7B8%7D%7B100%7Dx)
![\text{Selling price}=x+0.08x](https://tex.z-dn.net/?f=%5Ctext%7BSelling%20price%7D%3Dx%2B0.08x)
![\text{Selling price}=1.08x](https://tex.z-dn.net/?f=%5Ctext%7BSelling%20price%7D%3D1.08x)
The selling price of a ratio set is 72.00.
![72=1.08x](https://tex.z-dn.net/?f=72%3D1.08x)
![\dfrac{72}{1.08}=x](https://tex.z-dn.net/?f=%5Cdfrac%7B72%7D%7B1.08%7D%3Dx)
![x=66.666...](https://tex.z-dn.net/?f=x%3D66.666...)
![x\approx 67](https://tex.z-dn.net/?f=x%5Capprox%2067)
Therefore, the cost price for the radio set is 67.

Step-by-step explanation:
Answer:
B i think
Step-by-step explanation:
i think its B because all the other ones don'e look right. hope its correct. :)
A half-life of the isotope is 15 days and at start its mass is 32 g.
A table:
t: m:
0 32 g
15 16 g
30 8 g
45 4 g
60 2 g
75 1 g
In the first column is used an arithmetic sequence ( a 1 = 0, d = 15 ).
In the second column is used a geometric sequence ( a 1 = 32, r = 1/2 )
Answer:
7/16
