Rx + sx/t = 1<br> solve for x
Lubov Fominskaja [6]
Thanks for your question!

First thing we have to do here is take t to the other side by multiplication:

rx + sx = t

Now, group together, x as the GCF:

x(r+s) = t

Now, divide

x = t/(r+s)

Hope this helps!

The cheerleaders are selling tickets to a pasta dinner to raise money for new competition outfits. They plan to charge $6 per pe
kow [346]

Answer:

22 and a half ticket sold here will result in no profit situation for cheerleaders.

Step-by-step explanation:

The charge per person = $6

The total cost for dinner = $135

If cheerleaders do not make any profit , then

{ If the money earned from tickets  = The money Spent} ⇒ NO PROFIT

Now, charge per person = $6

So, number of person needed to earn a total of $135

n = \frac{\textrm{The total money needed}}{\textrm{Charge per person}}

n = \frac{135}{6} = 22.5

So, 22 and a half ticket sold here will result in no profit situation for cheerleaders.

If they sell 23 tickets, they will have a profit of $3

And if they sell 22 tickets, they will be short by $3.
