Answer 1

Answer:
`\$10.50`

Explanation:

Let be "b" the cost in dollars of each bag.

According to the information provided in the exercise, yo know that the total cost of 5 bus tickets that the Hipster Dance company purchases is:

`(\$150)(5)=\$750`

And they have 7 bags that cost "b" dollars each. So, the total cost of 7 bags can be represented with this expression:

`7b`

Since the total bill is $823.50, you can write the following equation to represent this situation:

`750+7b=823.50`

Solving for "b", you get:

`b=823.50-750\\\\b=(73.50)/(7)\\\\b=10.50`
