    Answer:

    Lin should expect to sell 10 cups more

    Step-by-step explanation:

    The line c = 2t − 89 relates the cups Lin expect to sale (c) with the high temperature of the day (t)

    If high temperature on Saturday is t1, then high temperature on Sunday is (t1+5)

    Cups sold on Saturday are: 2t1 − 89

    Cups sold on Sunday are:  2(t1+5) − 89 = 2t1 + 10 – 89

    Cups sold on Sunday – Cups sold on Saturday:

    2t1 + 10 – 89 – (2t1 − 89) = 2t1 + 10 – 89 – 2t1 + 89 = 10
