Answer:
$13.50
Step-by-step explanation:
First, we got to multiply $18 by 25% or .25
$18 x .25 = $4.50
Lastly, we just subtract $4.50 from $18.
$18 - $4.50 = $13.50
X equal 7 so 49=x7 that is what I would do at least

Answer:
Chips = 14
Pretzel = 14
Cookie = 8
Popcorn = 13
Question Mark = 222
Step-by-step explanation:
First Equation:
Chips + Pretzel + Chips = 42
Third Equation: Chips = Pretzel.
This means that
Pretzel + Pretzel + Pretzel = 42
Pretzel = 
Chips = Pretzel
Chips = 
Second Equation:
Cookie + Chips + Cookie = 30
We know that Chips = 14.
Cookie + 14 + Cookie = 30
Subtract 14 on both sides:
Cookie + Cookie = 16
Cookie =
.
Fourth Equation:
Cookie + Cookie + Popcorn = 29
We know that Cookie = 8.
8 + 8 + Popcorn = 29
16 + Popcorn = 29
Subtract 16 on both sides:
Popcorn = 13.
Question Mark:
(Popcorn + Popcorn)
Cookie + Chips = (13 + 13)
8 + 14 = 26
8 + 14 =
