Please help w/ algebra homework! I am required to take this class and have no clue about algebra.?

The equation C=mx+b can be used to model the monthly cost, C, of a cell phone plan where b is the flat monthly cost, m represents the cost in dollars per minute and x is the number of minutes used in the month. Choose a flat monthly rate and cost per minute and insert the values you have chosen for m and b into the equation. Then use this equation to find the total monthly cost, C, if 68 minutes are used.

    flat monthly rate = 30

    cost per min = 0.05

    C = .05(68) + 30

    ok so pick two numbers, lets go with 25 and 13.

    so b=25

    m = 13

    x= 68

    soooo

    C=13(68)+25

    C=1793

    all you got do is plug in numbers. read it slow.
