Step-by-step explanation:

Mathematically the profit can be calculated by subtracting the cost price from the selling price

Here, the cost price is $136

Now, their selling price is obtained by multiplying the number of pieces sold by the selling price of each piece

Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

$\frac{-3+7i}{-6-7i} \times \frac{-6+7i}{-6+7i} =\frac{18-21i-42i-49i^2}{(-6)^2-(7i)^2} \\=\frac{18-63i -49(-1)}{36-49i^2} \\=\frac{18+49-63 i}{36-49(-1)} \\=\frac{67-63i}{36+49} \\=\frac{67-63i}{85} \\=\frac{67}{85} +(\frac{-63}{85} )i\\$

$a=\frac{67}{85} \\b=\frac{-63}{85}$
