Question

A group 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?

Answer 1

The snorkels will cost 20.60 because you will have to divide 153 and 15 then when you get your total times it by 2 then you will get 20.60

Answer 2

Answer:  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.

$12x+15y=153\ \ \ ...(i)$

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

i.e. $x=3y...(ii)$

Put value of x in (i) , we get

$12(3y)+15y=153\\\\\Rightarrow\ 36y+15y=153\\\\\Rightarrow\ 51y=153\\\\\Rightarrow y=\dfrac{153}{51}\\\\\Rightarrow\ y=3$

Put  value of y in (ii) , we get $x=3\times3=9$

Hence, it cost $9 to rent a snorkel.
