Answer 1

Answer:

Cost to a rent a snorkel$=\ 12$                ,           Cost on 10 rent  snorkel $=\ 120$

Step-by-step explanation:

Given,

Tourist spend on rent snorkel and fin=$\ 168$

10 snorkel and 12 pairs of fin

Let the cost to  rent a snorkel be =x

and cost of a pair of fin is =y

x=3y            (given condition)

$10x+12y=168$

$10\times 3y+12y=168$

$30y+12y=168$

$42y=168$

$y=168/42$

$y=4$

Cost of a pair of fin=  $y=\ 4$

$x=3y$

$x=3\times 4$

$x=12$

Cost of rent a snorkel$=\ 12$

Total cost of a rent snorkel

$=10\times 12$

   =$\ 168$
