Hello!
Since we are rounding until tenths, the answer would be 3879.
Since a tenth is the first decimal of a number, we just round it and get that.

Answer:
90%
Step-by-step explanation:
First, find the total number of tickets sold.
810 discount + 90 full-price = 900 tickets
Now you need to find what percent 810 is of 900.
% of 900 = 810
810/900 = 0.9
Convert this to a percentage.
0.9 × 100% = 90%
90% of tickets were sold at a discount.

Answer: 20% discount</h3>
Work Shown:
amount saved = 84-67.20 = 16.80 dollars
Divide this over the original larger price to get 16.80/84 = 0.20 = 20%
Note how 20% of 84 = 0.20*84 = 16.80 to help check the answer.
Or we can say 0.80*84 = 67.20 which also helps confirm the answer.
The 0.80 is from the fact that you save 20% but still have to pay the remaining 80%
We find the inverse of equation y=x2-36 by solving for y and replace with variable x. Solving this, we transpose -36 to opposite side. Equation will now be y+36=x2, then we get the square root of y+36. We now have the missing inverse equation which is f−1(x)= sqrt (y+36), - sqrt (y+36).
