Question

The WipeOut Ski Company manufactures skis for beginners. Fixed costs are$\backslash (30$.Fill in Table 7.16 for total cost, average variable cost, average total cost, and marginal cost.

Quantity	Variable Cost	Fixed Cost	Total Cost	Average Variable Cost	Average Total Cost	Marginal Cost
$0$	$0$	$\backslash )30$
$1$	$\backslash (10$	$\backslash )30$
$2$	$\backslash (25$	$\backslash )30$
$3$	$\backslash (45$	$\backslash )30$
$4$	$\backslash (70$	$\backslash )30$
$5$	$\backslash (100$	$\backslash )30$
$6$	$\backslash (135$	$\backslash )30$

Short answer

Quantity	Variable Cost	Fixed Cost	Total Cost	Average Variable Cost	Average Total Cost	Marginal Cost
$0$	$0$	$\$30$	$\$30$	$0$	_	_
$1$	$\$10$	$\$30$	$\$40$	$\$10$	$\$140$	$$10$
$2$	$\$25$	$\$30$	$$55$	$\$12.50$	$\$27.50$	$\$15$
$3$	$\$45$	$\$30$	$\$75$	$\$15$	$\$25$	$\$20$
$4$	$\$70$	$\$30$	$\$100$	$\$17.50$	$\$25$	$\$25$
$5$	$\$100$	$\$30$	$\$130$	$\$20$	$\$26$	$\$30$
$6$	$\$135$	$\$30$	$\$165$	$\$22.50$	$\$27.50$	$\$35$

Step-by-step solution

Step 1. Given information 

Quantity	Variable Cost	Fixed Cost
$0$	0	$\$30$
$1$	$\$30$	$\$30$
$2$	$\$25$	$\$30$
$3$	$\$45$	$\$30$
$4$	$\$70$	$\$30$
$5$	$\$100$	$\$30$
$6$	$\$135$	$\$30$

Step 2. Total cost, average variable cost, average total cost, and marginal cost

Total cost = Fixed cost + Variable cost

Average Total Cost = Total cost / Quantity

Average Variable Cost = Variable cost / Quantity

Marginal Cost = Change in the total cost/Change in the quantity

Step 3. Result

Quantity	Variable Cost	Fixed Cost	Total Cost	Average Variable Cost	Average Total Cost	Marginal Cost
$0$	$0$	$\$30$	$\$30$	$0$	_	_
$1$	$\$10$	$\$30$	$\$40$	$\$10$	$\$40$	$\$10$
$2$	$\$25$	$\$30$	$\$55$	$\$12.5$	$\$27.5$	$\$15$
$3$	$\$45$	$\$30$	$\$75$	$\$15$	$\$25$	$\$20$
$4$	$\$70$	$\$30$	$\$100$	$\$17.5$	$\$25$	$\$25$
$5$	$\$100$	$\$30$	$\$130$	$\$20$	$\$26$	$\$30$
$6$	$\$135$	$\$30$	$\$165$	$\$22.5$	$\$27.5$	$\$35$
