What are the answer choices
Answer: The commercial costs $900 to produce and $110 each time it is aired.
Step-by-step explanation:
Let y represent the number of feet and x represent the number of minutes. Convert 22 1/2 to decimal form: 22.5
y = -22.5x
Plug in -315 for y
-315 = -22.5x
divide both sides by -22.5
14 = x
It will take 14 minutes.
