Please show your work... How do you do this?
I do not get how the answer is c(m)=0.9+0.6(5m1) especially where 5m1 comes from...please explain.
A taxicab charges $.90 for the first 1/5 mile and $.60 for each additional 1/5 mile. If a customer rides in this cab for m miles (m>1/5) , which of the following functions descibes the cost,c(m), of this tax ride in dollars?

MATH...... 
Anonymous,
There are five parts in the mile, and if the customer is riding more than 1/5 of a mile, then the first 1/5 of the mile is separate. All five parts cannot be included in the calculation since the .9 is separate.
