g In January, each of people purchased a $ washing machine. In February, % fewer customers purchased the same washing machine that had increased in price by %. What was the change in sales from January to February?

Change in sales=$2,400

Explanation:

Calculation for the change in sales from January to February

First step is to find the total sales in January

Total sales in January=60*$500

Total sales in January=$30,000

Second step is to find the selling price in February

Selling price in February=$500+$500*20%

Selling price in February=$500+$500*0.2

Selling price in February=$500+$100

Selling price in February=$600

Third step is to find the Number of purchase in February

Number of purchase in February=60-60*10%

Number of purchase in February=60-60*0.1

Number of purchase in February=60-6

Number of purchase in February=54

Fourth step is for us to find the sales in February by multiplying the number of purchase by the selling price in February

Sales in February=54*$600

Sales in February=$32,400

Last step is to the change in sales from January to February

Using this formula

Change in sales=Sales in February-total sales in January

Change in sales=$32,400-$30,000

Change in sales=$2,400

Therefore the change in sales from January to February will be $2,400
