The island taxi charges $5 for initial fee and $2 per mile.
For the island taxi to be $25 it would have to drive for 10 miles. (25-5=20) due to the initial fee puts you at 20. 20÷2 is 10. Meaning 10 miles for the island taxi.
Since the lyft charges a flat rate of $25 for any distance the only distance that matters is the island taxi.
One of the answers is equilateral because all of the sides are of equal length. The other answer is acute because all of the angles are under 90º since they are all 60º. Hope this helps!
