Let x equal the number of strawberries while y is the total amount of money she had.
The equation is: 2.25(x)+8.75=y.
Then, if she bought 4 pounds of strawberries, it would work as follows: 2.25(4)+8.75 is the total amount. That means 9+8.75 would be the total. Thus, the amount of money she started out with was 17.75 dollars.
