First, subtract all of the margins from the width to get 4 1/2 inches. Then, divide this by two to get 2 1/4.
Answer:
Answer A is correct.
Step-by-step explanation:
Please note the difference beteen f(x+3) and f(3).
So f(x + 3) means, where you see x in the equation, you substitute x+3. (This is a recursive entry).
f(x)= 2x² - 3
f(x)= -3 + 2x²
f(x)= -3 + 2* (x+3)²
f(x)= -3 + 2* (x+3) * (x+3)
f(x)= -3 + 2* (x² + 3x + 3x + 9)
f(x)= -3 + 2* (x² + 6x + 9)
f(x)= -3 + 2x² + 12x + 18
f(x)= 2x² + 12x + 18 -3
f(x)= 2x² + 12x + 15
So answer A is the correct answer
Find the price before the 15% profit:
2500 / 1.15 = 2173.91
Now multiply the original cost by 1 + 38%:
2173.91 x 1.38 = 2999.99
Answer: 2.999.99 ( may need to round to 3,000)
