$R (t) = \frac{76.8}{6.4 + 6 e^{- 0.02 \cdot 2180}}$

Step 1

Multiply $- 0.02$ by $2180$ .

$R (t) = \frac{76.8}{6.4 + 6 e^{- 43.6}}$

Step 2

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$R (t) = \frac{76.8}{6.4 + 6 (\frac{1}{e^{43.6}})}$

Step 3

Combine $6$ and $\frac{1}{e^{43.6}}$ .

$R (t) = \frac{76.8}{6.4 + \frac{6}{e^{43.6}}}$

Step 4

Add $6.4$ and $\frac{6}{e^{43.6}}$ .

$R (t) = \frac{76.8}{6.4}$

Step 5

Divide $76.8$ by $6.4$ .

$R (t) = 12$
