Question

Jillana takes a single dose of medication that remains in her body according to the equation r = 200(0.75)d, where r represents the amount of medication remaining after d days. If Jillana had taken the medication two days earlier, the amount of medication remaining in her system relative to the amount that remains in her system after d      days would be represented using the equation r2 = 200(0.75)d + 4. Which of the following is an equivalent equation?

Answer 1

i looked at another online and it said letter A. (Not 100% sure)

Answer 2

The equivalent equation of $r_2(d) = 200(0.75)^{d+4$ is $r_2(d) = 63.28125(0.75)^{d}$

How to determine the equivalent equation?

The equation is given as:

$r_2(d) = 200(0.75)^{d+4$

We start by applying the product law of indices

$r_2(d) = 200(0.75)^{d} * 0.75^4$

Evaluate the exponent

$r_2(d) = 200(0.75)^{d} * 0.31640625$

Rewrite as:

$r_2(d) = 0.31640625 * 200(0.75)^{d}$

Evaluate the product

$r_2(d) = 63.28125(0.75)^{d}$

Hence, the equivalent equation of $r_2(d) = 200(0.75)^{d+4$ is $r_2(d) = 63.28125(0.75)^{d}$
