Answer:

6 minutes

Step-by-step explanation:

Mr Crenshaw checks at a rate of 1/10 and Mr. Aguirre checks at a rate of 1/15.

If they work together, they will be checking at a combined rate of:

1/10 + 1/15 = [3(1) + 2(1)]/30

= 5/30 = 1/6

Their combined rate is 1/6 which means they check one set in 6 minutes

Tomas Briggs and Sons reviewed their first year operations. Gross sales were $204,000 Customer returns and allowances were $18,0
Masteriza [31]

Answer:

Percentage of total net sales = 91.17%

The percentage of cost of merchandise sold = 44.11 %

Percentage of First year expenses = 41.17 %

Percentage of Overall profit = 5.88 %

Step-by-step explanation:

Given:

Gross sales= $204,000

Customer returns and allowances = $18,000

Cost of the merchandise they sold = $90,000

overall profit before taxes = $12,000

Now,

The Net sales = Gross sales - sales returns  

or

The net sales = $204,000 - $18,000 = $186,000

Thus,

Percentage of total net sales = \frac{\textup{Net sales}}{\textup{Gross sales}}\times100

or

Percentage of total net sales = \frac{186,000}{204000}\times100

or

Percentage of total net sales = 91.17%

Now,

The percentage of cost of merchandise sold = \frac{\textup{cost of the merchandise sold }}{\textup{Gross sales}}\times100

or

The percentage of cost of merchandise sold = \frac{\textup{90,000}}{\textup{204,000}}\times100

or

The percentage of cost of merchandise sold = 44.11 %

And,

Percentage of First year expenses = \frac{\textup{Expenses}}{\textup{Gross sales}}\times100

or

Percentage of First year expenses = \frac{\textup{84000}}{\textup{204000}}\times100

or

Percentage of First year expenses = 41.17 %

also,

Percentage of Overall profit = \frac{\textup{Overall profit}}{\textup{Gross sales}}\times100

or

Percentage of Overall profit = \frac{\textup{12,000}}{\textup{204,000}}\times100

or

Percentage of Overall profit = 5.88 %
