The sales person is getting a commission of 3.5%. Thereore  she gets a commission of \$3.5 for every \$100 of sale. So to get a commission of \$1  she should make a sale amounting \$100/3.5 = \$28.5714 .

She got a commission of \$450.

Therefore to get a commission of \$450 , she should make a sale of  \$450*28.5714 = \$12857. 14

Therefore to get \$450 commission she should  sell  worth \$12858 (rounded to next integer).

To get a commission of  \$1 she sells

Let us assume the salesperson sold products worth \$ S. Now the commission that she makes is 3.5%.

And it is also given that the actual commission made was \$450.

Therefore we know that 3.5% of S is equal to 450.

=> (3.5/100) * S = 450

=> S = 450*(100 / 3.5)

=> S = 450*100 / 3.5

=> S = 45000/3.5

=> S= 12857.14

Therefore the cost of the products sold to make a commission of \$450 is \$12857.14
