Answer:

The third choice

Step-by-step explanation:

A company's sales increased 20% this year, to $6740. What were their sales last year?
Lesechka [4]

The sales last year of the company is 5617

<h3>How to determine the sales last year?</h3>

The given parameters are:

Company sales = 6740

Percentage increase = 20%

The sales of the company last year (x) to date is calculated as:

Company sales = (1 + Proportion) * Last year sales

Substitute the known values in the above equation

6740 = (1 + 20%) * x

Evaluate the sum

6740 = 1.2 * x

Divide both sides by 1.2

x = 5617

Hence, the sales last year is 5617
