if indeed the QT || RS, that simply means that QT is the midsegment of ∡PRS, but that also means that the corresponding sides of the small triangle ∡PQT and the larger one ∡PRS are in a proportion, meaning

$\bf \cfrac{PQ}{PR}=\cfrac{PT}{PS}~\hspace{5em}\cfrac{18}{18+38}=\cfrac{36}{36+80}\implies \cfrac{18}{56}=\cfrac{36}{116}\implies \cfrac{9}{28}\ne \cfrac{9}{29}~~\bigotimes$

Mustafa’s soccer team is planning a school dance as a fundraiser. The DJ charges $200 and decorations cost $100. The team decides to charge each student $5.00 to attend the dance. If n represents the number of students attending the dance, which equation can be used to find the number of students needed to make $1,500 in profit?

$5n - 300 = 1,500\\\\5n + 300 = 1,500\\ \\5n - 200 + 100n = 1,500\\\\5n - 100 -200n = 1,500$

Answer:

$5n - 300 = 1,500$

Step-by-step explanation:

Given:

Charges of DJ = $200

Decoration charges = $100

Profit need to be made = $1500

Charges per student to attend the dance = $5

We need to write the equation to find the number of students for to attend the dance in order to make profit.

Solution:

Let the number of student be represented by 'n'.

Now we can say that;

Profit to be made should be equal to Charges per student to attend the dance multiplied by number of students minus sum of Charges of DJ and Decoration charges.

framing in equation form we get;

$5n-(200+100)=1500\\\\5n-300=1500$

Hence the equation to find the number of students attending the dance is $5n - 300 = 1,500$
