Answer:
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 [tex]5d + 10 - 4 = 13.5[/tex]
Solving the equation,
[tex]5d + 6 = 13.5[/tex]
[tex]5d = 13.5 - 6[/tex]
[tex]5d = 7.5[/tex]
[tex]d = \frac{7.5}{5}[/tex]
[tex]d = 1.50[/tex]
The cost of 1 large drink is $1.50.
Therefore, Option A is correct.
5d + $10.00 – $4.00 = $13.50; $1.50
