This year, a small business had a total revenue of 73,600. If this is 28% more that their total revenue the previous year, what was their total revenue the previous year?

Let X be the total revenue of the business the previous year.

According to the given information, this year's total revenue is 28% more than the previous year's total revenue.

So, this year's total revenue = X + 0.28X = 1.28X

Given that this year's total revenue is 73,600, we can set up the equation:

1.28X = 73,600

Dividing both sides by 1.28:

X = 73,600 / 1.28
X = 57,500

Therefore, the total revenue of the business the previous year was $57,500.
