Jenna's band is going to record a CD at a recording studio. What is the cost for one day in the studio?

Question

Jenna's band is going to record a CD at a recording studio. They will pay $225 to use the studio for one day and $80 per hour for sound technicians. Jenna has $205 and can reasonably expect to raise up to an additional $350 by taking pre-orders for the CDs.

*"n" represents the number of hours in the studio

I also need to know: Jenna's band is willing to spend between $205 and $555. So, the total cost 225 + 80n must be in this range. The inequality that models this is ?≤ 225 + 80n ≤?

 

Answer 1

205 < 225 + 80N < 555

 

-20 < 80N < 320

 

-20/80 < N < 320/80

 

-1/4 < N < 4

 

She has to get it done in 3 hours or less
