in a class, 12 pupils are in a computer class and 3/4 of the remaining pupils are in the science club. If 1/5 of the pupils are neither in the computer nor science club, how many pupils are there in the class?

answer: 4 (:

step-by-step explanation:

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
