Answer:
WU corresponds with CD and the scale factor is 3
The answer that is correct is 6:3.
9) Original price: $45 ; discount rate : 20% off
Discount = $45 * 20% = $9
Sales price = $45 - $9 = $36
10) Original price : $450 ; discount rate : 30% off
Discount = $450 * 30% = $135
Sales price = $450 - $135 = $315
11) Original price : $48 ; discount rate : 15% off
Discount = $48 * 15% = $7.20
Sales price = $48 - $7.20 = $40.80
12) Original price : $150 ; discount rate : 25% off
Discount = $150 * 25% = $37.50
Sales price = $150 - $37.50 = $112.50
13) Original price : $1,450 ; discount rate : 40% off
Discount = $1,450 * 40% = $580
Sales price = $1,450 - $580 = $870
14) Original price : $82 ; discount rate : 50% off
Discount = $82 * 50% = $41
Sales price = $82 - $41 = $41
