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?

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
