The equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t
<h3>Equation</h3>
There are three basic types of equation in mathematics. Namely:
- Linear equations
- Quadratic equations
- Simultaneous equations
- Monthly fee = $50
- One-time joining fee = $150
- Total cost = C
- Number of months = t
C = 150 + 50t
Therefore, the equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t
