Answer:
x = 60
y = 200
Step-by-step explanations:
Selling price:
Price of program = $0.5
Price of music = $5
Cost of production :
Program = $0.15 per program
CD = $1.75 per CD
Total Revenue = $400
Total Profit = $265
Let
Number of CD's = x
Number of program's = y
(0.5y + 5x) = 400
0.5y = 400 - 5x
y = (400 - 5x) / 0.5
y = 800 - 10x (1(
Cost of production:
1.75x + 0.15y
Profit = Total Revenue - Total cost of production
5x + 0.5y - 1.75x + 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
Divide both sides by -0.25
x = -15/ -0.25
x = 60
y = 800 - 10x
= 800 - 10(60)
= 800 - 600
= 200
y = 200
