Cab Fare

A taxi cab charges $1.50 for the first 1/5 mile and 30 cents for additional 1/5 mile. Determine the cost of a 10 mile trip

having problem setting this word problem up

Normally, I'd suggest naming what it asks for. Rule #1 Name Stuff.

T = Total cost of 10 mile trip

That doesn't quite cut it on this one.

Really, on this one, we don't need any defintions. Everything is already given. We just need to build it.

First 1/5 mile costs $1.50

Okay, that's $1.50 and we have 10 mi - 1/5 mi = 50/5 mi - 1/5 mi = 49/5 miles left.

(49/5 miles) * 30¢ = ???

Add the $1.50 and you're done.
