Answer:
I agree with the student's answer. "x" cannot be -2 because then it would make -20 which is not equal to 20:
5(-2)(2) = ?
-10 x 2 = ?
? = -20
-20 ≠ 20
Step-by-step explanation:
Justificaiton:
5(x)(2) = 20
10(x) = 20
10/10(x) = 20/10
x = 2
Second Justification:
5(x)(2) = 20
5/5(x)(2) = 20/5
2x = 4
2x/2 = 4/2
x = 2

Step-by-step explanation:
You are given
a commission of $10 for $100 in sales. You are to find the commission for $150
in sales. It is stated in the problem that the salesman’s commission varies
directly as his sales. Directly means proportional, and so this relationship has
a constant. Let us say the salesman commission is c and his sales is s. Let us
also denote k as our constant.
C = ks
$10 = k($100)
k = 0.1
We need to find
the salesman commission in $150 sales.
C = ks
C = (0.1)($150)
<u>C = $15</u>
