Given that the grocer spent only $650 on marketing this year, you know that this is 54% of his marketing budget last year.
You can rewrite a percent as a Decimal Number by dividing it by 100:

Let be "x" the amount of money (in dollars) the grocer spent on marketing last year.
Knowing all the data, you can set up the following equation:

When you solve for "x", you get:


Hence, the answer is: He spent $1,413.04 .
