The restaurant's total cost is a mixed cost that depends on customers served. The restaurant's management uses the high-low method to estimate the variable and fixed components of this cost. If the management believes that the restaurant will be able to serve 16,000 customers in December, the restaurant's estimated total cost for December is closest to

$29,390

Explanation:

For computing the total cost first we have to determine the variable cost per customer and the fixed cost which is shown below:

Variable cost Per Customer is

= (High total cost - low total cost) ÷ (high number of customer served - low cost of customer served)

= ($28,934 - $28,241) ÷ (14,100 - 11,214)

= $0.24

Now

Fixed cost is

= High cost - (high number of customer served × variable cost per customer)

= 28,934 - (14,100 × 0.24)

= $25,550

So, the total cost for 16,000 customers is

= Fixed cost + variable cost

= $25,550 + (16,000 × $0.24)

= $29,390

i would say a penny hope it you
