Question

The cost, C, of producing n clocks can be found using the formula 21) C = 36 n + 81. What is the cost when no clocks are produced?

Answer 1

n=0 right? so its 81? or is it 0?

Answer 2

Yeah. Plug in 0 for n.

Answer 3

The answer is 324 but I don't understand how they got it. Its roots and radicals.

Answer 4

Answer 5

Do they provide an explanation?

Answer 6

it doesnt seem to make sense there

Answer 7

No there is a radical sign in front of the n +81

Answer 8

\[36\sqrt{n+81}\] ? is that it?

Answer 9

Oh ok. That makes sense.
\[C = 36\sqrt{n + 81}\]\[C = 36\sqrt{0 + 81}\]\[C = 36\sqrt{81}\]\[C = 36(9)\]\[C = 324\]
