Question

Hello could someone help me with a and c ? I keep getting those wrong

Answer 1

Explanation:

Part A

The price per item when q units are sold is given by the function:

`D(q)=-1.3q+260`

When 30 units are sold:

`\begin{gathered} \text{The price per item, }D(30)=-1.3(30)+260 \\ =-39+260 \\ =\$221 \end{gathered}`

Therefore, the total revenue from selling 30 items is:

`R(q)=30*221=\$6,630`

Part B

• Fixed Cost = $4000

,

• Variable Cost = $8 per Item

`\begin{gathered} \text{ Total Cost for 30 items, }C(q)=4000+(8*30) \\ C(30)=\$4,240 \end{gathered}`

Part C
