Maria's fixed amount = 100
Let each call price = 100
increased call price = 125
100 * 100 = x * 125
x = 80
So Maria should spend 80 in order to have the same total amount
So Maria should reduce 100 * (100-80)/100 = 20 %
Option E
Let each call price = 100
increased call price = 125
100 * 100 = x * 125
x = 80
So Maria should spend 80 in order to have the same total amount
So Maria should reduce 100 * (100-80)/100 = 20 %
