Yuko added a 15 percent tip when she paid her cab driver. if the fare was $25.50, what was the total amount she paid?

I believe the correct answer would be B. $30

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

you can not solvr this without numbers
