Fixed costs: 9500$
Variable costs : 10$ per item

If total cost for 50 items increases by 10%,
the cost will be \(1.1(9500 + 10*50) = 1.1(10000) = 11000\)

New variable cost per item will be \(\frac{11000 - 9500}{50} = \frac{1500}{50}\) = $30(Option D)

9500+10*50=10000
10000+10%of 10000=10000+1000=11000

Variable cost = VC
Fixed Cost + (VC per item)*(# of items) = Total Cost

Total cost increases by 10 percent.

The trap answer is B. Answer B gives a VC per item calculated as if the original total did not include fixed cost of $9,500.

Easiest way, IMO, is to focus on total cost for two scenarios, original and increased (new).

1) Original total cost to produce 50 items:

Fixed Cost + (VC per item)(# of items) = Total Cost
$9,500 + ($10)(50) = Original Total Cost
($9,500 + $500) = $10,000 = Original Total Cost

2) Total cost increases by 10 percent
($10,000*1.1) = $11,000= New Total Cost

3) New VC per item
Same Fixed Cost + (VC\(_{new}\))(# of items)= New Total Cost

$9,500 + (VC per item)*(50 items) = $11,000

(VC per item)*(50 items) = ($11,000-$9,500)

(VC per item)*(50 items) = $1,500

VC per item = \(\frac{$1,500}{50items}= $30\)

Let total cost be a and the new variable cost per item be b.

\(a = 9500 + 50(10) ----- 1\)
\(\frac{11a}{10} = 9500 + 50(b) --- 2\)

Divide Eqn 1 by 2, we get

\(b = 30\)
