Round answer to nearest hundreth.

A) $1555

Step-by-step explanation:

The formula for percentages is :

To work this out you would first need to find 16 percent of $2100. You can do this by first dividing the percentage by 100, this gives you 0.16. This is because percentages are out of 100.

The next step is to multiply 0.16 by 2100, this gives you 336. This is because by multiplying 16% as a decimal by the amount of 2100 we are working out 16% of 2100.

The next step is add up the value of all of the deductions. You can do this by adding 336 by 89 by 85 and 35, this gives you 545.

The final step is to minus the total deductions of 545 from the total amount of 2100, this gives you $1555.

1) Divide 16 by 100.

2) Multiply 0.16 by 2100.

3) Add 336 and 89 and 85 and 35.

4) Minus 545 from 2100.
