Therefore, the CD player X is worth buying, since it only costs 1,200.

CD player X: 1,200

CD player Y: 1,400

CD player Z: 1,350

Step-by-step explanation:

Formula:

discount amount/original price = discount%/100%

For CD player Z:

discount amount = x

original price/regular price = 1,800

discount% = 25%

For CD player Y:

discount amount = x

original price or regular price = 2,000

discount% = 30%

For CD player X:

discount amount = x

original price or regular price = 1,500

discount% = 20%

For CD player Z

x/1,800 = 25/100

x ⋅ 100 = 25 ⋅ 1,800

100x = 45,000

100x/100 = 45,000/100

x = 450

For CD player Y

x/2,000 = 30/100

x ⋅ 100 = 30 ⋅ 2,000

100x/100 = 60,000/100

x = 600

For CD player X

x/1,500 = 20/100

x ⋅ 100 = 20 ⋅ 1,500

100x = 30,000

100x/100 = 30,000/100

x = 300

Formula:

Sale price = original price - discount

For CD player Z: 1,800 - 450 = 1,350

For CD player Y: 2,000 - 600 = 1,400

For CD player X: 1,500 - 300 = 1,200
