First, solve the one time fee
$80 - 20 = $60
Next, solve the monthly fee
15 + 5 = 20
(a) The expression: Let x = month
20x + 60
(b) Remember the previous question.
<em>Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month. </em>

<em>Let x = months</em>
<em>20x + 60</em><em> is your expression</em>
No. In fact, it will be the same. Waiving the $20 off the one-time fee would give the same amount of one-time payment, 60. Membership and Mandatory equipment maintenance would also add up to $20 a month.
