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.

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=(153)/(51)\\\\\Rightarrow\ y=3`

Put value of y in (ii) , we get
`x=3*3=9`

Hence, it cost $9 to rent a snorkel.
