John and 3 friends are going out for pizza for lunch. they split one pizza and 4 large drinks. the pizza cost $13.00. after using a $6.00 gift certificate, they spend a total of $13.20. write an equation to model this situation, and find the cost of one large drink.

4d + $13.00 – $6.00 = $13.20; $1.60

3d + $13.00 – $6.00 = $13.20; $2.07

4d – $13.00 + $6.00 = $13.20; $6.73

4d + $13.00 – $6.00 = $13.20; $1.55

D is the correct answer.

Step-by-step explanation:

You would add $6.00 to $13.20, making 19.20, subtracting 4 x $1.55 (6.2) leaves you with $13, the cost of the pizza. So therefore, it would be 4d + $13.00 – $6.00 = $13.20; $1.55.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
