As a salesperson, your commission is directly proportional to the dollar amount of sales you make. If your sales are $800, your commission is $112. How much commission would you earn if you had $1,400 in sales?

Answer: $196

Step-by-step explanation:

Let C = Commission from sales

Let S = Sales amount

From the question, C is directly proportional to S

C α S

C = k. S (where k is a constant)

k = C/S

When C = $112 and S = $800,

k = 112/800

k = 0.14

Therefore;

C = 0.14S

When S = $1400

C = 0.14*1400

C = $196

The commission if your sales are $1400 is $196
