EXAMPLE 1

Layla earns $400 per week plus $15 per customer she signs up. Let "C" represent the number of customers. Write an expression to show how much she earns in a week.


Layla automatically earns $400 that week (this is her constant)
She earns $15 per customer (15 times the number of customers)

Expression: 15c + 400

Therefore is she signs 3 customers, we can easily plug that in for the value of c.
