what are the dollars per jacket "x" in R(x) = 85 sqrt(x) when 402 have have been produced?

1 answer

The function R(x) gives the cost in dollars of producing x jackets.

To find the dollars per jacket "x" when 402 jackets have been produced, we need to evaluate R(402):

R(x) = 85sqrt(x)

R(402) = 85sqrt(402)
= 85*20.0499 (rounded to four decimal places)
= 1704.2442

So the cost of producing 402 jackets is $1704.24.

To find the cost per jacket, we divide the total cost by the number of jackets produced:

Cost per jacket = Total cost / Number of jackets produced
= $1704.24 / 402
= $4.24 (rounded to two decimal places)

Therefore, the cost per jacket when 402 jackets have been produced is $4.24.
