at the end of the month , a certain ocean desalination plant ’ s reservoir contained 26 million gallons of water . this amount is eighth the normal level . if this amount represents 65 % of the reservoir ’ s total capacity , how many million gallons short of total capacity is the normal level ?
"the q talks of total capacity , normal level , present level , shortage etc . . so it is all about not going wrong in these terms 26 mg = 65 % of total . . total = 26 / . 65 = 40 mg . . normal level = 1 / 8 of 40 = 5 mg . . shortage of normal level = 40 - 5 = 35 mg . . c"
divide(divide(26, const_2), divide(65, const_100))
