Answer 1

$8

Explanation:

A group of tourists spends $156 to rent snorkels and fins.

They rented 15 snorkels and 18 pairs of fins.

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

Let us assume that the rental cost of a pair of fins is x, so the rental cost of snorkel will be 4x.

Then total cost of 15 snorkels and 18 pairs of fins will be,

`=15(4x)+18x`

`=60x+18x`

`=78x`

But it is given as $156, so

`\Rightarrow 78x=156`

`\Rightarrow x=2`

Therefore, the rental cost of a pair of fins is $2 and cost of snorkel is
`2* 4=\$8`
