Answer: $466.
Step-by-step explanation:
Add all the numbers in the graph together, you get 194.
Now, subtract 194 from 660, you get 466. That's how much profit the company makes.
108 = ( x)(48-x)
108 = 48x - x^2
48x -x^2 -108 = 0
I'm assuming you're doing solve the square right now, so you should be able to do the rest.
1/2 because everything lose half its value points wise.
28.50x + 110.99(14-x)=811.45
distribute
28.50 x + 1553.86-110.99x =811.45
combine like terms
-82.49x+1553.86=811.45
subtract 1553.86 from each side
-82.49x =-742.41
divide by -82.49
x=9
He bought 9 of the 28.50 features and 5 of the 110.99 features
