Question

Last week, Rohana bought a new computer for 10% off the advertised price. The advertised price was $1,800. How much did Rohana have to pay for the computer?

Answer 1

10% of 1800 is 180. If she payed 180 ten times it would be 1800 dollars. The computer is 180 dollars off. 1800-180= 1620. She pays $1620
