Answer:
50 cents The red on the right end.
Step-by-step explanation:
Let the chocolate chip cookies = x
Let the jumbo popcorn = y
Julie
y + 2x = 5
Marvin
y + 4x = 6 Subtract
-2x = - 1 The y's disappear. You are left with 1 dollar (negative). Divide by - 2
-2x/-2 = - 1 / -2
x = 1/2
x = 0.5 or 50c
Each cookie costs 50c
To solve
if you have |a|=b, solve a=b and a=-b
|4x+12|=16
solve
4x+12=16 and 4x+12=-16
minus 12 both sides
4x=4 and 4x=-28
divide both sides by 4
x=1 and x=-7
