Answer:

An equation for the total cost of using a computer for t minutes is [tex]C(t)=4+0.20t[/tex]

Step-by-step explanation:

Fixed charge of using computer = $4

The cafe charges $0.20 for every minute

We are supposed to find the total cost of using a computer for  t minutes

Cafe charges for 1 minute = $0.20

Cafe charges for t minutes = $0.20t

So, Total charge = Fixed charge +0.20t

Total charge =4 +0.20t

We are given that C(t), representing the total cost of using a computer for t minutes

So,[tex]C(t)=4+0.20t[/tex]

Hence an equation for the total cost of using a computer for t minutes is [tex]C(t)=4+0.20t[/tex]
