    Cab fare problem

    How should I go about solving this problem,

    Suppose I were to take a 163.79 mile cab ride. If the cab fare cost, $0.01 for the first mile, $0.02 for the second, and double for each mile thereafter, what would be the total cost?

    hi

    total cost= $0.01+$0.02+2($0.02)(161)+(0.79 x 0.04)=$6.502

    You have a geometric series whose first term is 0.01 and common ratio is r = 2. Determine how many terms you need and substitute into the usual formula.
