Since x represents the year, year 15 will be 15 years.
Plug in "15" as your "x"
y = -2(15)^2 + 36(15) + 6
15^2 = 225 (Exponents come before multiplication)
y = -2(225) + 36(15) + 6
y = -450 + 540 + 6
y = 90 + 6
y = 96
<em>The answer is B</em>

Step-by-step explanation:
selling price = original cost + markup value
We need to find the markup
markup = original cost * markup percent
= $784.50 * 6.5%
= $784.50 *.06.5
=50.9925
Rounding to the nearest cent
=50.99
selling price = original cost + markup value
=784.50+50.99
