Answer: The dollar sales volume will be $4000
Step-by-step explanation:
Let x represent the amount of sales volume for which the two offers result in the same pay.
Company A offers a weekly salary of $360 plus a commission of 18% on their dollar sales volume. This means that the total value offered by company A for x sales volume is
360 + 0.18x
Company B offers a weekly salary of $720 plus commission of 9% on their dollar sales volume. This means that the total value offered by company B for x sales volume is
720 + 0.09x
For the two offers to be the same, the sales volume would be
360 + 0.18x = 720 + 0.09x
0.18x - 0.09x = 720 - 360
0.09x = 360
x = 360/0.09
x = $4000
P(x) = (x^2)(x - 4)^2(x + 4) + some constant(b)
2025 = (1^2)(1 - 4)^2(1 + 4) + b
2025 = 45 + b
b = 1980
Complete Equation:
p(x) = (x^2)(x - 4)^2(x +4) + 1980
or expanded form
p(x) = x^5 - 4x^4 - 16x^3 + 64x^2 + 1980
You'd do $500 x 0.15 to which gives you 75$ in tax. $500 + $75 = $575 selling price
I'm sorry the picture is blurry. Could you post another one.
