Answer: Cost per pair of jeans = $ 20
Cost per pair of shorts = $12
Cost per shirt = $8
Step-by-step explanation:
Let x= cost per pair of jeans
y = Cost per pair of shorts
z= cost per shirt.
For you, total cost = x+4y+2z= 84
For your friend, total cost = 2x+y+3z=76
For cousin, total cost = x+2y+z= 52
Required system:
from (i), (*)
put this in (ii) and (iii) we get
from (iv),
Hence, x= 20, y= 12 , z=8
So, Cost per pair of jeans = $ 20
Cost per pair of shorts = $12
Cost per shirt = $8
<h2>Answer:</h2><h2>If she continues to throw darts 75 more times, she could predict to hit the
</h2><h2>bull's-eye 15 times.</h2>
Step-by-step explanation:
Shay found that she hit the bull's-eye when throwing darts times =
.
In five times, she will hit the dart once.
If she continues to throw darts 75 more times,

If she continues to throw darts 75 more times, she could predict to hit the
bull's-eye 15 times.
