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

$=10\times 12$

= $\$ 168$

You and your friend each collect rocks and fessis your friend collects three times as many roots and half as many fossils as you

n200080 [17]

Answer:

Number of rocks and fossils collected by you is 1 and 24 respectively

Number of rocks and fossils collected by your friend is 3 and 12 respectively

Step-by-step explanation:

Let the number of Rocks you collect be x

Let the number of Fossils you collect be y

Then the total number pf objects you collected will be

x + y = 25

x = 25 - y------------------------------(1)

Your friend collects three times as many rocks and half as many fossils as you.

This can be written as

3x + y (1/2) = 15

3x + (y/2) = 15-------------------(2)

Substituting (1) in (2)

3(25 - y) + (y/2) = 15

75 - 3y + (y/2) = 15

Grouping the like terms we get,

75 - 15 = 3y = (y/2)

60 = ( 6y - y /2)

60 x 2 = 6y -y

120 = 5y

y = 120/5

y = 24

Substituting y value in equation(1) we get

x = 25 - 24

x= 1

y= 24

Friends collects 3 times rock

so collects 3x =3(1) = 3rocks

Also he collects half as many fossils

That is

y/2 = 24/2 = 12 fossils

Hope this help you! :)
