Problem 1
Brittany Berrier became a famousskater. She won 85% of her meets. If she had 250 meets in2000, how many did she win?
Problem 1: Ignore extraneous 2000
Amount = Rate x Base
Rate = 85 % or 85/100 or .85
Base = 250
A = .85 x 250
A = 212.50
Problem 2
Krystyl Ferguson workedat the zoo. If 3 of her 17 baboons were sick, what % were sick?

35 = .28 Base.28
Base = 35÷.28
Base = 125
