Question

A landscape supply business charges $35 to deliver mulch. The cost of the mulch is $29.
per cubic yard. Write and solve a linear equation to find the cost of having 6 cubic yards
of mulch delivered to a site.
Slope intercept form

Answer 1

Answer:

$209

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept (initial value)

Let

x ----> the volume of mulch in cubic yards

y ----> the total cost in dollars

we have that

The slope of the linear equation is

$m=29\ \frac{\ }{yd^3}$

$b=\ 35$ ----> flat fee to deliver mulch

The linear equation is

$y=29x+35$

For x=6 yd^3

substitute in the equation and solve for y

$y=29(6)+35$

$y=\ 209$
