3.80 x 5 = 19
So $19 dollars spent on beads for a 5 necklaces.
37.50 - 19 = 18.5
18.5 ÷ 5 = 3.7
So $3.7 per pendant.
Hope it helps!
You need to post the diagram that goes to this question. But here's a hint so you can do this on your own co planar means that the points are in the same plane and collinear means that the points are on the same line.
Answer:
40 more paintings in order to maximize sales making a total of 60 paintings
Step-by-step explanation:
Let x= no.of copies above 20
Total Sales(x) = (number of copies)(price per copy)
Sales (x)= (20 +x)(100 –x)
Open bracket
=1200-20x+100x-x^2
=1200+80x-x^2
Derivative of the sales
80-2x=0
80=2x
Divide both sides by 2
40=x
Because Sales(x)= –2, this is maximal by the second derivative test
The artist should make 40 more paintings in order to maximize sales making a total of 60 paintings.
