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
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

Vince went on a 3 day hiking trip. Each day, he walked 3/4 the distance that he walked the day before. He walked 83.25 kilometers total in the trip. How far did Vince walk on the 1st day of the trip?
Assume vince walked x km on the first day .
The following equation can be formed
x + 3/4 x + (3/4)^2 x = 83.25
x + 0.75x + 0.5625x = 83.25
Add the like terms
2.3125x = 83.25
Divide both sides by 2.3125
x = 36 km.
