To reduce the price by 20% you first have to find 10%.
We do this by dividing the number by 10.
In this case 10% would be 2.8
We can the double this to get 20%, therefore 20% is 5.6
We need to take this 20% off of the original $28
28-5.6= $22.40
The $2 coupon need to be taken off the price which leaves $20.40
Janet will pay $20.40 for the necklace.
