in a certain warehouse , 30 percent of the packages weigh less than 75 pounds , and a total of 48 packages weigh less than 25 pounds . if 80 percent of the packages weigh at least 25 pounds , how many of the packages weigh at least 25 pounds but less than 75 pounds ?
n0 = 30.0
n1 = 75.0
n2 = 48.0
n3 = 25.0
n4 = 80.0
n5 = 25.0
n6 = 25.0
n7 = 75.0
t0 = 100.0 - n4
t1 = n2 / t0
t2 = t1 * 100.0
t3 = n0 * t2
t4 = t3 / 100.0
answer = t4 - n2
