Answer 1

C. 60%

Explanation:

Consider 1st row of table

Total Price = P= 22.50

Discount=D=13.50

Percent discount=(D/P) x 100

=(13.5/22.5) x 100

= 60%

Consider 2nd row of table

Total Price = P= 27

Discount=D=16.20

Percent discount=(D/P) x 100

=(16.2/27) x 100

= 60%

Now we know discount rate is r=60%
