linear equation

Question

A landscaping company charges $40 per cubic yard of mulch plus a delivery charge of $22. Find a linear equation which computes the total cost C (in dollars) to deliver  cubic yards of mulch.

Answer 1

The basic formula for this is total = base + variable.

In this case, that is C = 40 + 22x.

Answer 2

C=40x+22 is the correct equation because it costs $40 per cubic yard times x number of cubic yards
