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

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

Thus,

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

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

Percentage of total net sales = 91.17%

Now,

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

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

The percentage of cost of merchandise sold = 44.11 %

And,

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

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

Percentage of First year expenses = 41.17 %

also,

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

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

Percentage of Overall profit = 5.88 %

Jami is keeping track of the weather for a class project she recorded data on 16 days out of 16 days 1/4 were clear blue skies h

katovenus [111]

Answer:

4 days

Step-by-step explanation:

She recorded date for 16 days, and 1/4 of the days were clear blue skies.

One way to find this is to multiply 16 and 1/4

16*1/4=4

Another way is to first convert 1/4 to a decimal

1/4=0.25

Then multiply 16 and 0.25

16*0.25 =4

So, 4 out of 16 days had clear blue skies
