I got ECHA... hope it's right:)
Answer:
1. 14 = 2 + 12
2. 16 = 4 + 12
3. 18 = 6 + 12
4. 20 = 8 + 12
Step-by-step explanation:
Super easy. All you do is replace the numbers in your table with the corresponding letter. In this case we have a table of s and f.
Example for row two: f = s + 12. Replace s with 4 ( 4 is from your s column so you would replace it with that) then solve and plug in your answer (When you solve your answer, it will go under f column).16 = 4 + 12 . f = 16, s = 4.
Formula = f = s + 12.
1. 14 = 2 + 12
2. 16 = 4 + 12
3. 18 = 6 + 12
4. 20 = 8 + 12
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
The y function
hope this helps
