The price of one ticket is $ 62.2
<h3><u>Solution:</u></h3>
Given that a performer expects to sell 5000 tickets for an upcoming event
They want to make a total of $ 311, 000 in sales from these tickets
<em><u>To find: price of one ticket</u></em>
Let us assume that all tickets have the same price
Let "a" be the price of one ticket
So the total sales price of $ 311, 000 is obtained from product of 5000 tickets and price of one ticket


Thus the price of one ticket is $ 62.2

Answer:
Danielle is 7 and her counselor is 21
Step-by-step explanation:
Let x be the age of Danielle and y be the age of her counselor then:
y=3x
x+y=28
We can solve this using substitution. In this case, substitute 3x for y since y=3x...
x+3x=28
    4x=28
Divide both sides by 4 (division property of equality)
x=7
y=3x=3(7)=21
Danielle is 7 and her counselor is 21
