Using linear function concepts, it is found that the unit rate in dollars per square yard is of $1.35 for Company A and of $2.05 per Company B.
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem, for company A, the function is:
A: C = 1.35y + 100.
For company B, the function is:
B: C = 2.05y.
Considering the slopes, the unit rate in dollars per square yard is of $1.35 for Company A and of $2.05 per Company B.
