20% is 20 for each 100
As a fraction it is 20%2F100=2%2F10=1%2F5,
and 20%2F100=0.2
As a decimal, 20% is 0.2
20% of 377,610 is a discount of 377610%2A0.2=75520

10% is 10%2F100=1%2F10 as a fraction,
and 10%2F100=0.1
As a decimal, 10% is 0.1
10% of 200,021 is a discount of 200021%2A0.1=20002.1

The total discount on the 2-instrument package is
75520%2B20002.1=95524.1

The total list price before the discount was
377610%2B200021=577631

What percentage of 577631 is 95524.1?
As a fraction/decimal it is it is
65524.1%2F577631=655241%2F5776310=approximately0.165 (rounded)
As a percentage (rounded) that is 16.5%
