Answer:
<u>The correct answer is A. R(d) = -54d2 + 1,269d + 10,530 </u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Price per seat when the average attendance is 810 fans = $ 13
For every $2.00 increase in average ticket price, the attendance decreased by an average of 27 fans per game.
2. Which equation shows the revenue, R, as a function of d, the number of $2.00 increases over $13.00?
R(d) = (13 + 2d) (810 - 27d)
R(d) = 10,530 + 1,620d - 54d² - 351d
R(d) = -54d² + 1,269d + 10,530
<u>The correct answer is A. R(d) = -54d2 + 1,269d + 10,530 </u>
On solving the linear equation, There are in total 24 unshaded squares and 16 shaded squares.
<h3>What is a linear equation?</h3>
Ax+By=C is the usual form for two-variable linear equations. A typical form linear equation is, for instance, 2x+3y=5. When an equation is provided in this format, finding both intercepts is rather simple (x and y).
squares, where x= number of squares
2x = shaded squares
Number of unshaded squares = 3x.
This is due to the fact that there are 3 times as many unshaded squares as there are shaded squares (2 times more unshaded = 3*). (shaded)
Overall, there are 40 squares (5 * 8), therefore 40 total squares—shaded and unshaded—are present.
2x+3x = 40
5x = 40
x = 40/5
x = 8
There are 3×8 = 24 unshaded squares
8×2 = 16 shaded squares in all.
Therefore, you may shade in 8 squares whatever you choose.
