A cell phone plan costs $30 per month for unlimited calling plus $0.15 per text message.

a.) Write a linear model that represents the monthly cost of this cell phone plan if the user sends t text messages.

b.) If you send 200 text messages, how much would you pay according to this cell phone plan?

A linear equation can be defined as an equation of the straight line with one variable and one constant. A general linear equation is y=mx+b, where a first-order (linear) term x with the slope m and b is a constant and is the y-intercept.

Given Information:

A cell phone plan costs $30 per month for unlimited calling plus $0.15 per text message.

Part A:

If the user sends t text messages, then the linear equation can be written as,

y = 0.15 t + 30

Where the slope m is 0.15 with variable t and y-intercept b is 30.

Part B:

If you send 200 text messages, then the total cost of the plan is given as,

[tex]T = 0.15\times 200 + 30[/tex]

[tex]T = 60[/tex]

Hence we can conclude that the total cost of the plan for 200 text messages is $60.
