Question

Mia wanted to purchase a computer for $500.00. The store offered 30% off. If the people arrived by 9am, they will get an additional 10% off. Find the cost of the computer is mia got to the store by 9.am.

Answer 1

In order to determine the costs of the computer, first calculate the 30% of the original price of the computer, just as follow:

(30/100)(500.00) = 150.00

then, with the 30% of discount the price is:

500.00 - 150.00 = 350.00

next, for people arrived by 9am there is an additional 10% off, then, you have:

(10/100)(350.00) = 35.00

and the final price of the computer is:

350.00 - 35.00 = 315.00

The final price is $315.00
