Brockman Corporation's earnings per share were $3.50 last year, and its growth rate during the prior 5 years was 9.2% per year.

Answer:

c. 12.48

Step-by-step explanation:

The earnings per share after t years can be modeled by the following equation:

$E(t) = E(0)(1+r)^{t}$

In which E(0) is the earnings last year and r is the growth rate, as a decimal.

Brockman Corporation's earnings per share were $3.50 last year, and its growth rate during the prior 5 years was 9.2% per year. Growth rate maintained.

This means that $E(0) = 3.50, r = 0.092$

$E(t) = E(0)(1+r)^{t}$

$E(t) = 3.50(1+0.092)^{t}$

$E(t) = 3.50(1.092)^{t}$

If that growth rate were maintained, how many years would it take for Brockman's EPS to triple?

This is t for which E(t) = 3*E(0) = 3*3.50 = 10.50.

$E(t) = 3.50(1.092)^{t}$

$10.50 = 3.50(1.092)^{t}$

$(1.092)^{t} = \frac{10.50}{3.50}$

$(1.092)^{t} = 3$

$\log{(1.092)^{t}} = \log{3}$

$t\log{1.092} = \log{3}$

$t = \frac{\log{3}}{\log{1.092}}$

$t = 12.48$

So the correct answer is:

c. 12.48

You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost?

Novay_Z [31]

Well all you would have to do is subtract 25 to 5 which is 5 so $20 is how much
