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.
