Question

"The cost of a workout class ls 2 cases for $7 .The number of classes, c independent variable) proportional to the cost, m. (dependent variable )

Write an equation to represent the relationship between c and m Now we write a new equation if classes c is the dependent variable and cost m is the independent variable.

A) c = 2m
B) m = 2c
C) c = m + 2
D) m = c - 2

Answer 1

To represent the relationship between the number of workout classes and the cost, use the equation c = m/7. If classes are the dependent variable and cost is the independent variable, the correct equation is c = 7m.

Step-by-step explanation:

To represent the relationship between the number of workout classes, c, and the cost, m, we can use the equation c = m/7, because the cost of 1 workout class is $7. This equation shows that the number of classes is directly proportional to the cost, with a constant rate of 1/7.

If we want to write a new equation with classes, c, as the dependent variable and cost, m, as the independent variable, we need to isolate c. So the correct equation is c = 7m.

Therefore, the answer is B) c = 7m.
