Answer:
Drinks= $3.50 popcorn=$4.25
Step-by-step explanation:
Let medium popcorn=m
Let drinks= d
Equation 1: m+3d=14.75
Equation 2: 2m+5d=26

Multiply Equation 1 by 2 and compare to find d
Substitute d into equation 2 to find price of medium popcorn
Answer:
x=72.5
Step-by-step explanation:
2x-35-15=95 (common factors go together)
2x-50=95 (add 50 to both sides)
2x=145 (divide both sides by 2)
x = 72.5
