WITCHER [35]

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

$=10\times 12$

= $\$ 168$
