Answer : The cost of 10 balls will be, 13.5 dollars
Step-by-step explanation :
As we are given the following expression:

where,
P = total price (in dollars)
n = number of balls used
Given:
n = number of balls used = 10
Now we have to determine the cost of 10 balls.




Thus, the cost of 10 balls will be, 13.5 dollars
10% of $2,000 is $200.
30%=3*10%
Therefore:
30% of $2,000 is $600.
