Answer:
Part a) The linear model that represents the monthly cost of each plan is
<em>Plan A</em>
<em>Plan B</em>
Part b) The plans cost the same for 100 GB of data
Step-by-step explanation:
Part a) Write a linear model that represents the monthly cost of each plan if the customer uses g GB of data
Let
g -----> the GB of data
y -----> the monthly cost
we know that
The linear equation that represent each plan is equal to
<em>Plan A</em>
----> equation A
<em>Plan B</em>
----> equation B
Part b) After how many GB of data will the plans cost the same?
Equate equation A and equation B and solve for g
therefore
The plans cost the same for 100 GB of data
