A computer cost £900. It is on sale for 25% off. You also need to pay 6% sales tax. What is the final price of the computer?
1 answer:
First we have to find 25% of 900 pounds (i hope that's the right currency). so 900 x .25 = 225
so we subtract 225 from 900 and get 675 pounds.
to find sales tax we have to find 6% of 675, so 675 x .06 = 40.50
675 + 40.50 = 715.5 pounds
