Answer:
a)
<u>The discount id 40%, so the function is:</u>
b)
- p = 100 ⇒ d = 40
- p = 200 ⇒ d = 80
- p = 300 ⇒ d = 120
- p = 400 ⇒ d = 160
- p = 500 ⇒ d = 200
<em>The graph is attached</em>
c)
- p = $85 ⇒ d = 0.4*$85 = $34
<u>Sale price is:</u>
- CP = p - d = $85 - $34 = $51
√3 x √5 = √15
7√15 - 2√15 = answer 5√15

The computer cost is $3000
Step-by-step explanation:
The given is:
- The ratio of the price of a tv to the price of a computer is 13 : 15
- The tv 400 dollars cheaper than the computer
We need to find the cost of the computer
Assume that the price of the computer is $x
∵ The ratio between the prices of the tv and the computer is 13 : 15
∵ The price of the computer is $x
∵ The price of the tv 400 dollars cheaper than the computer
- That means the price of the tv is less than the price of the
computer by $400
∴ The price of the tv is $(x - 400)
By using the ratio method
→ tv : computer
→ 13 : 15
→ (x - 400) : x
By using the cross multiplication
∴ 15(x - 400) = 13(x)
- Simplify the left hand side
∴ 15x - 6000 = 13x
- Add 6000 to both sides
∴ 15x = 13x + 6000
- Subtract 13x from both sides
∴ 2x = 6000
- Divide both sides by 2
∴ x = 3000
The computer cost is $3000
