Question

A company that manufactures memory chips for digital cameras uses the formula c equals 120 cube root of n squared end root plus 1300to determine the cost c, in dollars, of producing n chips.

How much will it cost to produce 250 chips?

Answer 1

The cost:C = 120 · ∛(n²) + 1,300We have to produce 250 memory chips for digital cameras:n = 250C ( 250 ) = 120 · ∛(250²) + 1,300 = = 120 · ∛62,500 + 1,300 = = 120 · 39.685 + 1,300 = = 4,762 + 1,300 = $6,062Answer: It will cost $6,062.

Answer 2

$6062

Explanation:

The formula we are given is

`c=120\sqrt[3]{n^2}+1300`

We will replace n with 250:

`c=120\sqrt[3]{250^2}+1300\\ \\=120\sqrt[3]{62500} +1300\\\\=120(39.685)+1300\\\\=4762.20+1300\\\\=6062.20 \approx 6062`
