Value of the CD after 3 months is given by 300(1 + 0.03 / 4) = 300(1 + 0.0075) = 300 x 1.0075 = $302.25.
Therefore, interest for 3 months = $302.25 - $300 = $2.25
The total sale of the bedding set including 5% sale tax is $69.66
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Discount = 20% of 86 = 0.2 * 86 = 17.2
Selling price of bed = 5% of 17.2 = 0.05 * 17.2 = 0.86
Total sale = 86 - 17.2 + 0.86 = 69.66
The total sale of the bedding set including 5% sale tax is $69.66

Answer:
60 CDs
Step-by-step explanation:
Given that :
Price of program = $0.5
Price of music = $5
Cost of production :
Program = $0.15 per program
CD = $1.75 per CD
Revenue made= $400
Profit made = $265
Number of CD produced =?
Let Number of CD's = x and program = y
$(0.5y + 5x) = 400
Y = (400 - 5x) / 0.5
y = 800 - 10x
Production :
$(1.75x + 0.15y)
Total cost of production - Revenue made = profit
(1.75x + 0.15y) - (5x + 0.5y) = 265
1.75x + 0.15y - 5x - 0.5y = 265
1.75x - 5x 0.15y - 0.15y = 265
3.25x + 0.35y = 265 - - - (2)
Put y = 800 - 10x in (2)
3.25x + 0.35y = 265
3.25x + 0.35(800 - 10x) = 265
3.25x + 280 - 3.5x = 265
-0.25x = - 15
x = 15/ 0.25
x = 60
