Juan is getting a cab to travel 5 miles home. The cab is charging him %.50 for the first (1/5) mile and $.20 for all additional (1/10) miles. What is the total for his cab ride.

Solution

1/5 is equivilant to 2/10
:
5 miles is equivilant to 50/10
:
so if we subtract 2/10 from 50/10 we get 48/10(additional miles)
:
so we have $.5 + $.2(48)=.5+9.6=$10.1 total
