  1. Answer:

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

    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,C(t)=4+0.20t

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