Agroup of tourists spends $153 to rent snorkels and fins. a total of 12 snorkels and 15 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?

 It cost $9 to rent a snorkel.

Step-by-step explanation:

Let x = cost of each snorkel. and y = Cost of each pair of fins are rented.

Given : Amount spent by group of tourists to rent snorkels and fins. = $153

A total of 12 snorkels and 15 pairs of fins are rented.

Renting a snorkel costs three times as much as renting a pair of fins.

i.e.

Put value of x in (i) , we get

Put  value of y in (ii) , we get

Hence, it cost $9 to rent a snorkel.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
