Answer:

a.  $ \frac{\textbf{17}}{\textbf{4}} $

b.  $ \frac{\textbf{3}}{\textbf{8}} $

Step-by-step explanation:

a. $ \textbf{3} \hspace{1mm} \textbf{+} \hspace{1mm} \textbf{1}\frac{\textbf{1}}{\textbf{4}} $

A mixed fraction of the form $ a\frac{x}{y} = a + \frac{x}{y} $

$ \therefore 3 + 1\frac{1}{4} = 3 + 1 + \frac{1}{4} $

$ = 4 + \frac{1}{4} $

$ = \frac{\textbf{17}}{\textbf{4}} $

b. $ \textbf{2} \hspace{1mm} \textbf{-} \hspace{1mm} \textbf{1}\frac{\textbf{5}}{\textbf{8}} $

A mixed fraction of the form $ -c\frac{a}{b} = - c - \frac{a}{b} $

$ \therefore 2 - 1\frac{5}{8} = 2 - 1 - \frac{5}{8} $

$ = 1 - \frac{5}{8} $

$ = \frac{8 - 5}{8} $

$ = \frac{\textbf{3}}{\textbf{8}} $

Hence, the answer.

A company pays 12% commission on sales less than $7,000.00. 14% commission on sales
aleksandrvk [35]

Answer:

<em>The total commission is: $840 + $1,120 + $672 = $2,632</em>

Step-by-step explanation:

<u>Multi-Level Commissions</u>

For sales less than $7,000, a company pays a 12% commission.

For sales between $7,000 and $15,000, the company pays 14%.

For sales greater than $15,000, the company pays 15%.

Let's calculate the commission on sales of $19,480.

For the first $7,000, the commission is:

12*7,000/100 = $840

The remaining sales base is now $19,480-$7,000 = $12,480

For the portion of $8,000 between $7,000 and $15,000, the commission is:

14*$8,000/100 = $1,120

The remaining sales base is now $12,480 - $8,000= $4,480

This portion gets the final 15%:

15*$4,480/100 = $672

The total commission is: $840 + $1,120 + $672 = $2,632
