percent rate problem 7:
example: Helen paid $ 60 for a pair of shoes, that was listed for $ 80.
question: What rate of discount did she receive?
answer:
given: part (reduced price) = $ 60 base value (listed price) = $ 80
wanted: rate (rate of discount)
formula:
rate = part : base value * 100
rate = 60 : 80 * 100
rate = 75 %
100 % – 75 % = 25% rate of discount
answer:
She received a 25% rate of discount.
