Hello Online Teachers,
Would someone kindly help me with this college algebra course problem? I'm not sure where to start or how to end.
Problem: The owner of a health food store determines that the demand equation for selling a nutritional supplement is p= 18 - 0.5 sqrt (x-4) where p is the price in dollars and x is the number of bottles demanded per week. How many bottles are demanded per week if the price of the supplement is $13.50?
Best I can do so far is:
13.50 = 18 - 0.5 sqrt (x-4)
4.50 = -0.5 sqrt (x-4)
4.50 = -0.25 sqrt (x-4)^2 (x-4)^2
Now I'm stuck. Would I multiply -0.25 with both (x-4)^2 or did I flub up all of it? :?
How do I know which term to move first and from which side to start first or next?
Gratitudes for your sharing your time and knowledge,
Julia
