A sandwich shop has a catering program. There is a flat fee of $30.00 plus $5 per boxed lunch (sandwich, cookie, and bottled water) ordered. If a total order is $150 , how many boxed lunches were ordered?
Solve using this equation: 30+5x=150. And solve as follows: -30 on both sides to get 5x=120. Divide by 5 on both sides to get x=24. Meaning 24 boxes were ordered. You can always double check work by substituting your answer for the variable in the initial equation. 30+5(24)=150. 30+120=150. 150=150 so you know it works.
