Question

-Write a real-world situation that could be represented by the equation 12.5x + 30 = -7.5x + 90.5.

Answer 1

Answer:

3.025 (I think)

Step-by-step explanation:

12.5x + 30 = -7.5x + 90.5.

Add 7.5x on both sides

20x + 30 =  90.5

Subtract 30 on both sides

20x= 60.5

divided 20 on both sides

X = 3.025..

(sorry if it's wrong!)

Answer 2

Answer:

Imagination

Step-by-step explanation:

12.5x + 30 = -7.5x + 90.5.

12.5x + 30 = -7.5x + 90.5.

20x =60.5

x = 3 1/5

The sales from a music event comes from x tickets sold, at $12.50 a ticket, plus a rental income fee of $30 for an advertising billboard behind the stage.

The cost of the performance includes a musician's fee of $7.50 per ticket sold, plus a $90.5 rental fee for the stage.

The equation will tell us the number of tickets, x, that must be sold to break even (Inclome on the left and expenses on the right).

We need to sell at least 3 1/5 tickets to break even.  It's going to be close.
