John and 4 friends are going out for pizza for lunch. they split one pizza and 5 large drinks. the pizza cost $10.00. after using a $4.00 gift certificate, they spend a total of $13.50. write an equation to model this situation, and find the cost of one large drink.
a. 5d + $10.00 – $4.00 = $13.50; $1.50
b. 4d + $10.00 – $4.00 = $13.50; $1.88
c. 5d + $10.00 – $4.00 = $13.50; $1.70
d. 5d – $10.00 + $4.00 = $13.50; $4.88

the answer is A

Step-by-step explanation:

Option A - 5d + $10.00 – $4.00 = $13.50; $1.50

Step-by-step explanation:

Given : John and 4 friends are going out for pizza for lunch. They split one pizza and 5 large drinks. The pizza cost $10.00. After using a $4.00 gift certificate, they spend a total of $13.50.

To write : An equation to model this situation, and find the cost of one large drink.

Solution : Let d be the cost of the drink.

Number of drinks is 5.

The cost of 5 drink is 5d.

The pizza cost $10.00.

Total cost = 5d+$10

After using a $4.00 gift certificate, they spend a total of $13.50.

The equation to model the situation is

Solving the equation,

The cost of 1 large drink is $1.50.

Therefore, Option A is correct.

5d + $10.00 – $4.00 = $13.50; $1.50

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
