Final answer:
The equations that model the relationship between variables c and w are c = w - 3 and w = c + 3, stating c is 3 less than w and w can be expressed in terms of c, respectively.
Step-by-step explanation:
The question involves setting up equations that describe the relationship between the variables c and w. The first piece of information tells us that variable e is more than variable w, which can be written as e > w. However, for the relationship between c and w, the information provided states that c is 3 less than w. This translates into the equation c = w - 3. It is logical to assume that if c is given by w minus something, the second equation connecting w to c directly would just be the inverse of the first, which is w = c + 3. These two equations model the relationship stating that c is dependent on w and w can also be expressed in terms of c.
