Question

Janet receives a $6$% commission for selling boxes of greeting cards. If she sells $12$ boxes for 40$ each, how much does she earn?

• A. $27$
• B. $28$
• C. $28.8$
• D. $29.2$

Answer 1

The correct option is C $28.8$

The cost of each box is $40$
Janet got $6$% commission for selling boxes
So for each box she got $\frac{6}{100}\times 40=2.4$
For $12$ boxes, she will get $2.4\times 12=$28.8$.
