John and 4 friends are going out for pizza for lunch. they split one pizza and 5 large drinks. the pizza cost $12.00. after using a $5.00 gift certificate, they spend a total of $14.25. write an equation to model this situation, and find the cost of one large drink.

John + 4 friends is a total of 5 people

5 people = 5 drinks 1 pizza

5 people = 5 drinks + 12$

5people = 5 drinks + 12$ -5$

5 people = drinks + 7$

5 people = 7.25$ for drinks + 7 for pizza

7.25 for 5 drinks = 1.45

1 drink = 1.45

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

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
