DVDs can be made in a factory in Colorado at the rate of 10 DVDs per $1.50, but the factory costs $100,000 to build. If they make 1 million DVDs, what is the unit cost per DVD? Help ASAP please

1 DVD costs 15 cents.

I million DVDs cost 150,000 dollars.

Step-by-step explanation:

If 20 DVDs $3

then, 1 DVD x

20x = 3

x = 3/20

x = 0.15

1 DVD costs 15 cents

i already did this problem in one of my quizzes

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
