A landscaping company charges $41 per cubic yard of mulch plus a delivery charge of $26. Find a linear function which computes the total cost C (in dollars) to deliver x cubic yards of mulch.

Answer 1

Hello Tamera,

Let's focus on the phrase "A landscaping company charges $41 per cubic yard of mulch plus a delivery charge of $26"

1. $41 per cubic yard of mulch means 41 * number of cubic yards of mulch: so $41 for 1 cubic yard, $82 for 2 cubic yards...$164 for 4 cubic yards. Basically you MULTIPLY $41 by the number of cubic yards. Therefore, if you have x cubic yards of mulch, it will be $41 * x
2. "PLUS a delivery charge of $26" means you take $41 * x and ADD $26 to it to get the total cost

As a result, the total cost C will be given as: C = 41x + 26
