Suppose there is a simple index of two stocks - stock a and stock b. stock a
opens on monday with 7500 shares at $4.75 per share. stock b opens on
monday with 2500 shares at $8.95 per share. stock a opens on tuesday at
$4.50 per share, and stock b opens on tuesday at $8.15 per share. both
stocks have the same number of shares that they opened with on monday.
what is the rate of change of this simple index over 1 day?

A.

Step-by-step explanation:

<3

mean, 40.6

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
