Item 9 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

12

Step-by-step explanation:

s = rental price of snorkels

f = rental price of pair of fins

10s + 12f = 168

s = 3f

We know that s is the same as 3f so replace s with 3f in 1st equation and solve for f

10(3f) + 12f = 168

30f + 12f = 168

42f = 168

f = 168/42

f = $4.00 to rent a pair of fins

s = 3f = $12.00 to rent a snorkel

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
