PLEASE HELP may give brainliest if it helps At Sports Shoe Warehouse, the cost of 6 pairs of volleyball shoes is $570 plus $65 for
each additional pair. From Winning Team Shoes, the cost of 6 pairs of volleyball shoes
is $480 plus an additional 9% for each additional pair. For how many total pairs of
volleyball shoes does each vendor cost about the same?
About 19 pairs
about 10 pairs
about 17 pairs
about 18 pairs

About 10 Pairs , B I guess?

Step-by-step explanation:

Okay looks long but let's break it down.

Here's the main points :

6 pairs = $570 + ( $65 for each additional pair )

Another shop ( Let's not deal with the names )

6 pairs = $480 + ( 9% of $480 for each additional pair )

So let's solve them first. What is 9% of $480?

$480 × 9% = $480 × 0.09

= $43.2

So which means, in Winning team shoes ( oops have to deal with them names at the end ) , every pair of shoes bought will be a $43.2 for each additional pair.

Next, we need to calculate the cost of a pair of shoe.

In Sports Shoes Warehouse, every 6 pairs will cost you $570 + ( $65 × 6 )

So calculate!

$570 + ( $65 × 6 ) = $570 + $390

= $960

We need the cost of one shoe :

6 pairs of shoe costs $960, so divide by 6.

$960 ÷ 6 = $160

So one pair of shoe in Sports Shoe Warehouse is $160.

Onward!

Now, we need the individual cost for Winning Team Shoes

There, every 6 pairs of shoe will cost you $480 with $43.2 added for each pair.

So calculate!

$480 + ( $43.2 × 6 ) = $480 + $259.20

= 739.2

6 pairs of shoe costs $739.2, so divide $739.2 by 6.

$739.2 ÷ 6 = $123.20

So 1 pair of shoe costs $123.20.

Now towards how many total pairs of volleyball shoes will the vendor cost about the same?

The only way to find out, is the traditional way

( Correct me if I'm wrong )

Traditional Way :

The Trial-and-error way

Multiply them, then subtract their product, since the question wanted cost about the same. We find the most possible outcome.

A. About 19 pairs

B. About 10 Pairs

C. About 17 Pairs

D. About 18 Pairs

Multiply!

In 19 pairs, $160 x 19 and $123.20 × 19

So :

$160 x 19 = $3040

$123.20 x 19 = $2340.8

Subtract their products :

$3040 - $2340.80 = $699.2

Nope.

In 10 pairs, $160 x 10 and $123.20 x 10

So :

$160 x 10 = $1600

$123.20 x 10 = $1232

Subtract their products :

$1600 - $1232 = $368

Perhaps, but let's see it all.

In 17 pairs, $160 x 17 and $123.20 x 17

So :

$160 x 17 = $2720

$123.20 x 17 = $2094.40

Subtract, once again.

$2720 - $2094.40 = $625.60

Nope.

In 18 pairs, $160 x 18 and $123.20 x 18

$160 x 18 = $2880

$123.20 x 18 = $2217.60

Finally, subtract-

$2880 - $2217.60 = $662.4

So,

19 pairs would have be $699.20,

10 pairs would be $368,

17 pairs would be $625.60 and finally

18 pairs is $662.40

So I guess 10 pairs would be our best answer since they would look like they costed about the same.

So the answer should be About 10 pairs

angle uzt is congruent to angle tzy. angle vzw is congruent to angle yzx.
