20,000 records should be looked

Solution:

Solve for s :  50 = [1.96*s/0.5]

25 = 1.96s

s = 12.75

Solve for "n":  n = [1.96*12.75/0.25]^2

n = [100]^2

n = 20,000

Wexpro, Inc., produces several products from processing 1 ton of clypton, a rare mineral. Material and processing costs total $6
JulsSmile [24]

Answer:

$26,800

Explanation:

Sales revenue after further processing:

= Units produced from each ton of clypton × Selling price per unit

= 7,300 × $15

= $109,500

Sales revenue at split off point:

= Units produced from each ton of clypton × Selling price per unit

= 7,300 × $10

= $73,000

Incremental revenue:

= Sales revenue after further processing - Sales revenue at split off point

= $109,500 - $73,000

= $36,500

Incremental profit = Incremental revenue - Incremental cost

                              = $36,500 - $9,700

                              = $26,800

Therefore, financial advantage (disadvantage) of further processing product X15 is $26,800.

maks197457 [2]

Answer:

Cost of goods sold is $7,700

Gross Profit is $2,300

Explanation:

Cost of goods sold is Cost of goods available for sale less ending merchandise inventory. Ending merchandise understated by $300 means ending merchandise was accounted $300 less. So, $300 need to be added to ending merchandise. No ending merchandise is $2,300 (2,000 + 300)

Cost of goods sold will be 10,000 - 2,300 = $7,700

Gross profit is sales revenue less cost of goods sold which is computed as shown below:

Gross profit = 10,000 - 7,700

                    = $2,300
