Answer
Y=4/3x+1
The studio Cost per day as a function of the number of hours used by the sound technician and the inequality which models the data is :
- T(n) = 225 + 80n
- $205 ≤ (225 + 80n) ≤ $545
<u>Total studio cost</u> :
(studio fee per day + sound technician fee per hour)
If the Number of hours spent in studio = n
Total studio cost, T(n) = 225 + 80n
Amount at hand = $205
Additional earning from pre-orders = $340
This means that minimum amount Jenna can afford = amount at hand = $205
The maximum amount Jenna can afford = (Amount at hand + additional earning) = ($205 + $340 = $545)
Therefore in other to afford studio cost :
Minimum ≤ Studio cost ≤ maximum amount
$205 ≤ (225 + 80n) ≤ $545

Are there choices? I would say 4x1x3, or 12 options after the color is chosen.
x² + 3x - 4
rewrite with two middle terms that add to give three but multiply to yield -4
x² + x - 4x - 4
by factorizing
x(x + 1) - 4(x + 1)
⇒ (x - 4) (x + 1) = x² + 3x - 4
