Question

A group of tourists spends $168 to rent snorkels and fins. A total of 10 snorkels and 12 pairs of fins are rented. Renting a snorkel costs three times as much as renting a pair of fins. How much does it cost to rent a snorkel?

Answer 1

Let s = snorkel

Let f = fin

10s + 12f = 168
s = 3f

This is your system of equations.
