Solve by writing a variation equation. If distance is held constant, the time it takes to travel that distance is inversely proportional to the speed at which one travels. If it
takes 19 hr to travel the given distance at 78 mph, how long would it take to travel the same distance at 57 mph?

hr to travel the same distance at 57 mph.

f(x)=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
