Sady had 6 sheets of animal stickers. each sheet had the same number of stickers. a friend gave him 4 more animal stickers. now he has 40animal stickers. how many animal stickers were on each sheet?

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

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

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
