Tyra is designing an obstacle course in the shape of a rectangle if tire increases the length and width of the obstacle course by a factor of three what will be the resulting effect on the perimeter of the new playground

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

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
