Answer:

Answer 1

Answer: 13

Explanation: 1st plug in Catera’s price ($232) in the place for p. (232 = 284- 4q)
In order to find the q, or the quantity you want to isolate it. You can do this by subtracting 284 from 232. (Don’t forget forget to cancel out the 284 on the right side of the equal sign!) Subtracting 284 from 232 will give you the number -52. Your equation now should look like this —> -52 = -4q. ( Remember you want to isolate q entirely, it should stand alone.) Then divide both sides of the equation by -4 which will equal 13.
