Final answer:
The equation that models Suzy's monthly membership amount is m = 12 + 2c, where m is the total amount she pays and c represents the number of group exercise classes. To solve for c, isolate c on one side of the equation. The equation for c is c = (m - 12) / 2.
Step-by-step explanation:
The equation that models the amount of Suzy's membership for one month is m = 12 + 2c, where m represents the total amount she pays for her membership and c represents the number of group exercise classes she attends. To solve the equation for c, we need to isolate c on one side of the equation. Here's the step-by-step process:
Start with the equation m = 12 + 2c.
Subtract 12 from both sides of the equation: m - 12 = 2c.
Divide both sides of the equation by 2: c = (m - 12) / 2.
Therefore, the equation for c is c = (m - 12) / 2.
