Answer:
gloves cost $5
hats cost $4
Step-by-step explanation:
four pairs of gloves and four hats for $36.00
4g + 4h = 36
three pairs of gloves and four hats for $31.00
3g + 4h = 31
-------------------------
Subtract the second equation from the first
4g + 4h = 36
-( 3g + 4h = 31 )
––––––––––––
g = 5
gloves cost $5
substitute for g = 5 into either equation
4(5) + 4h = 36
20 + 4h = 36
Subtract 20 from both sides
4h = 16
Divide both sides by 4
h = 4
hats cost $4
Answer:
B. y = x - 2
Step-by-step explanation:
The sale price (y) is $2 less than the original price (x - 2).
To test this out, if a book's original price is $10..
x = 10
Using y = x - 2 and to test out if it works, we'll plug in x = 10 to discover y.
y = 10 - 2
y = 8
