Example Question #81 : Linear Equations
Ashley and friends ate dinner at a restaurant together, and they split the bill evenly. If each person paid , how much was the total bill?
Let be the total bill.
Since there is a total of people, we can write the following equation:
To solve for , multiply both sides by .
The total bill cost .
Example Question #82 : Linear Equations
Aaron was baking cupcakes. The recipe calls for cups of flour. If he has already put in cups of flour, how many more cups of flour does he need?
Let be the number of cups of flour he needs to still add.
Since he has already added cups, we can write the following equation:
To solve for , subtract both sides by :
Example Question #83 : Linear Equations
Last Monday, Adam had . Over the course of the week, he earned some money babysitting. He now has . How much money did he earn babysitting?
Let be the amount he earned babysitting.
Since he started out with , we can write the following equation:

Adam earned babysitting.
Example Question #84 : Linear Equations
Anna ran more miles than Nelson ran. If Anna ran miles, how many miles did Nelson run?
The miles that Nelson ran cannot be determined.
Let be the number of miles that Nelson ran.
Since we know that Anna ran more miles than Nelson did, we can write the following expression to tell us how many miles Anna ran in terms of :
Since we know that Anna ran a total of miles, we can then write the following equation:
Nelson ran miles.
Example Question #85 : Linear Equations
Steve has remaining after paying for a salad. How much money did Steve have before buying the salad?
