Answer:

The total yearly cost is $300 at each gym for 50 visits.

Step-by-step explanation:

Healthy Gym: 6n = t

Fitness Gym: 50 + 5n = t

When n = 50 visits, then...

Healthy Gym: 6(50) = $300

Fitness Gym: 50 + 5(50) = $300

How to solve this??<br><br> (r^-7b^-8) ^0<br> -------------<br> (t^-4w)

keeping in mind that anything raised at the 0 power, is 1, with the sole exception of 0 itself.

$\bf ~~~~~~~~~~~~\textit{negative exponents}
\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad a^n\implies \cfrac{1}{a^{-n}}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\cfrac{(r^{-7}b^{-8})^0}{t^{-4}w}\implies \cfrac{1}{t^{-4}w}\implies \cfrac{1}{t^{-4}}\cdot \cfrac{1}{w}\implies t^4\cdot \cfrac{1}{w}\implies \cfrac{t^4}{w}$
