To calculate the amounts mentioned in question 21 and 22, we need to apply the given rates to the respective sales amounts. Let's break it down step by step:

Question 21:
The first part says "$1,000 plus 6% on sales of $2,000."

To calculate the 6% on sales of $2,000, we multiply $2,000 by 0.06 (which is 6% written as a decimal):
$2,000 * 0.06 = $120.

Next, we add the $1,000 to the result:
$1,000 + $120 = $1,120.

Therefore, the amount in question 21 is $1,120.

Question 22:
The second part says "$500 plus $10 on sales of $1,400."

To calculate the $10 on sales of $1,400, we add $10 directly to $1,400:
$1,400 + $10 = $1,410.

Next, we add the $500 to the result:
$500 + $1,410 = $1,910.

Therefore, the amount in question 22 is $1,910.
