When the vat rate is 15% a customer pays 1610 to buy an electric iron .find the cost of the iron without vat (solve by video)

Schach [20]

Answer:

Cost without vat is 1,368.5

Step-by-step explanation:

Here, we want to know the cost of the iron without the vat.

From the question , we can see that 15% VAT brought the cost to 1610.

This means that the original cost without vat is 100% -15% = 85% of the total

Thus;

85/100 * 1610 is the cost without vat

And that is;

136850/100 = 1,368.5
