Problem
500 students wore blue and 300 students did not. What percent of all the students attending the game wore blue?
Result
62.5% of all the students attending the game wore blue.
Solution
We can calculate the percent of students wearing blue, after finding the total amont of students, using division and multiplication.
Let's add
500 + 300 = 800
Let's divide
800/500 = 0.625
Let's multiply
0.625 · 100 = 62.5
101 + d = 180
d = 79
91 + c = 180
c = 89
95 + a = 202
a = 107
b + 107 = 178
b = 71
Answer is A, since -25+-24 = -49
