Start with defining the variable.
Algebraic Expression: 25-1.5d
To write an algebraic expression of the given situation, we should first define the variable. The amount of gas changes each day meaning the variable will be the number of days.
| Verbal Expression | Algebraic Expression |
|---|---|
| Initial amount of gas (gal) | 25 |
| Decrease in the amount of gas each day (gal) | 1.5 |
| Number of days | d |
| Multiply the decrease by the number of days | 1.5* d |
| Subtract from the initial number of gallons | 25- 1.5 d |
