3 \frac{1}{2}  -2 \frac{5}{7} = \frac{(3\cdot2)+1}{2} -  \frac{(2\cdot7)+5}{7} =  \frac{7}{2} -  \frac{19}{7} \\\\= \frac{7\times 7}{2\times 7} -  \frac{19\times 2}{7\times 2} =  \frac{49}{14} - \frac{38}{14} \\\\= \frac{49-38}{14} =\boxed{\bf{\frac{11}{14}}}

You are offered two different sales jobs. The first company offers a straight commission of 5% of the sales. The second company
sweet [91]

Answer:$5408

Step-by-step explanation:

The first company offers a straight commission of 5% of the sales. This means the salary or income is 5% of sales made.

The second company offers a salary of $260 per week plus 4% of the sales. This means salary or income

= $260 +4% of 260

= 260 + (4/100)×260

= 260 +(0.04×260)

=260+10.4 = $270.4

Let x = the amount of sales you would have to sell in a week in order for the straight commission offer to be at least as good

5% of x should be greater than or equal to $270.4

0.05x = 270.4

x = 270.4/0.05 =$5408

The sales should be greater than or equal to $5408
