Asalesman's commission varies directly as his sales. if the commission is $10 for $100 in sales, find the commission for $150 in sales. a. $12 b. $15 c. $20 d. $25 the answer is b.)$15

Let the commission is represented by c and sales is representes by s.

Since there is a direct relationship between them, so the equation is

Where k is the constant of proportionality .

Now we substitute the given values of c and s and solve for k, that is

Dividing both sides by 100

Now we again use the same formula with s=150 and solve for c, that is

Correct option is B .

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
