,\left[x \right] = \left[ \frac{-2}{3}+\frac{\left( -4\right) \,y}{3}+\frac{z}{3}\right][x]=[​3​​−2​​+​3​​(−4)y​​+​3​​z​​]
\left[X \right] = \left[ 5+6\,y - 2\,z\right][X]=[5+6y−2z]
\left[x \right] = \left[ 2+\frac{3\,y}{2}+\frac{ - z}{2}\right][x]=[2+​2​​3y​​+​2​​−z​​]

Norman makes $15 commission for selling $200 in merchandise. he makes $37.50 commission for selling $500 in merchandise. assumin
vladimir2022 [97]

So he needs to sell $2,000 in merchandise.

<h3>what is the total value of merchandise he needs to sell?</h3>

We can assume that we have a proportional relation:

y = k*x

Where y is the commission and x is what Norman sells, then:

$15 = k*$200

k = $200/$15 = 0.075

$37.50 = k*$500

k = $500/$37.50 = 0.075

Then the relation is:

y = 0.075*x

If he wants a commission of $150, then:

$150 = 0.075*x

$150/0.075 = x = $2,000

So he needs to sell $2,000 in merchandise.
