Week 18, Day One
HW # 62 - Study for the Individual Exam
Warm up
Mr. Lee had a bag of red beans and a bag of black beans. 20%
of the total number of beans were black, and there were 180
oz. more red beans than black beans. He transferred some
red beans to the bag containing black beans so that the bag
now contained 30% of the total number of beans. How many
ounces of beans were there in the bag of mixed beans?
Warm Up Response
Since each part is 20%
20% x 3 = 60%
3 equal parts are 60%
60%  180 oz
10%  180 oz / 6 = 30 oz
10% of the total number of beans was 30oz
30 %  30 oz * 3 = 90 oz
There were 90 oz of beans in the bag of mixed
