Answer:
5$
Step-by-step explanation:
Lets call the childrens ticket x and the adult (x+3).
We then have the equation
200(x+3) + 100(x) = 2100
Divide all by 200
(x+3) + 1/2(x) = 10.5
Subtract 3
x + 1/2x = 7.5
Rewrite it
1.5x = 7.5
Divide by 1.5
x = 5
To solve for the inverse of the function given;
We begin by re-writing the function as follows;
To now find the inverse, we interchange y for x, and vice versa, as shown below;
We now find the value of y;
