Solving the Question

We're given:

• The popcorn is 120 calories per serving
• 120 calories is 25% fewer calories than original popcorn
• We must find the calorie count per serving of the original popcorn

Determine Variables

Let x equal the calorie count per serving of the original popcorn.

Create an Equation

The light popcorn has a calorie count of 120, which is 25% fewer calories than regular popcorn. This means that 75% of the calorie count of regular popcorn is equal to that of the light popcorn:

$x*0.75=120$

Solve the Equation

$x*0.75=120$

⇒ Divide both sides by 0.75:

$\dfrac{x*0.75}{0.75}=\dfrac{120}{0.75}\\\\x=160$

Answer

Therefore, each serving of regular popcorn has 160 calories.
