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 = [tex]\frac{42}{3} =14[/tex]
Chips = Pretzel
Chips = [tex]14[/tex]
Second Equation:
Cookie + Chips + Cookie = 30
We know that Chips = 14.
Cookie + 14 + Cookie = 30
Subtract 14 on both sides:
Cookie + Cookie = 16
Cookie = [tex]16\div 2 =8[/tex].
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) [tex]\times[/tex] Cookie + Chips = (13 + 13) [tex]\times[/tex] 8 + 14 = 26 [tex]\times[/tex] 8 + 14 = [tex]208+14=222[/tex]
