Answer:
They made a $531 commission.
Step-by-step explanation:
The given is:
- The price of each TV is $885
- The commission is 18% on every TV sold
- The salesperson sold 4 TV's
We need the value of the commission
Let us find the commission of every TV, then find the total amount of all
∵ The price of each TV is $885
∵ The commission is 18 %
→ Find 18% of $885
∴ The commission on every TV = 885 × 15%
∴ The commission on every TV = 885 × 15/100
∴ The commission on every TV = $132.75
∵ The salesperson sold 4 TV
∴ The commission on them = 4 × 132.75
∴ The commission on them = $531
They made a $531 commission.
<span>(5+2 i)(4-3i) - (5-2yi)(4-3i)
Factorize out (4 -3i)
(4 -3i)( (5 +2i) - (5 -2yi) )
= </span><span><span>(4 -3i)(5 +2i - 5 + 2yi)</span>
= </span><span><span>(4 -3i)(5 - 5 + 2i + 2yi)</span>
= (4 -3i)(2i + 2yi)
= (4 - 3i)(2 + 2y)i. Let's multiply the first two.
</span>
(4 - 3i)(2 + 2y) = 2*(4 -3i) + 2y*(4 - 3i)
= 8 - 6i + 8y - 6yi
= 8 + 8y - 6i - 6yi
(4 - 3i)(2 + 2y)i = (8 + 8y - 6i - 6yi)i Note: i² = -1
= 8i + 8yi - 6i² - 6yi²
= 8i + 8yi - 6(-1) - 6y(-1)
= 8i + 8yi + 6 + 6y
= 6 + 6y + 8i + 8yi
= (6 + 6y) + (8 + 8y)i In the form a + bi
X + y = 19
10x + 4y = 100
This is a systems of equations.
Isolate x from the first equation:
x = 19 - y
Now, plug it into the second:
10(19 - y) + 4y = 100
190 - 10y + 4y = 100
-6y + 190 = 100
-6y = -90
y = 15
Plug y in and solve for x:
10x + 4(15) = 100
10x + 60 = 100
10x = 40
x = 4
