Word Problems Involving the One-Step Equation – Example 1

How many packs of popcorn (p) can you buy for $52 if one package costs $4?
Solution:
List keywords and phrases in the problem to write the equation.
Each package costs $4.
The total money is $52.
How many packs of popcorn is p.
The model is a multiplication equation. \(4.p=52\)
Solve it by the inverse operation. \(4.p=52→p=52÷4=13\)
You can buy 13 packs of popcorn for $52.

Word Problems Involving the One-Step Equation – Example 2

At a restaurant, Maria and her three friends decided to divide the bill evenly. If each person paid $21 then what was the total bill (b)?
Solution:
List keywords and phrases in the problem to write the equation.
There were 4 people.
Each person paid $21.
What was the total bill b.
The model is a division equation. \(\frac{b}{4}=21\)
Solve it by the inverse operation. \(\frac{b}{4}=21→b=21×4=84\)
The total bill was $84.
