Question

The amount that a craftsman will charge for an item depends on the

amount that he spends on materials, m, and is determined by the
equation a = 2.5 + 2.5m, where a is the amount charged for each
item. What is the value of the dependent variable, if the value of the
independent variable is 3?

Answer 1

$10

Explanation:

m is the independent variable, and a the dependent one.

If m = 3, a = 2.5 + 2.5(3) = 10

The craftsman charges $10 when m = 3.
