The probability is 3/16.
The probability that she catches the bus on one of the days is 3/4; the probability she does not on the other day is 1/4. Together we have
3/4(1/4) = 3/16
Keep in mind that an inverse function is simply the reversal of the x and y coordinates of the parent function. For every (x,y) of the parent function, the inverse function has a point (y,x). With the conceptual part out of the way, finding the inverse function is relatively straight forward. If:
y=5x then the inverse function will be what you have when you solve for x and then reverse the variable labels...ie.
y=5x so
x=y/5 now reverse the variable labels...
y=x/5 this is the inverse function of y=5x or as your problem notation stated:
f^-1(x)=x/5
We are given that popularity of television is inversely proportional to its cost.
let us say popularity of television is represented by "P" and cost of television by "T".
We will use a constant "k" to convert the proportionality sign to equal to (=) sign.
Thus forming the equation :

We are given that 15 customers buy a television that cost $1500.
plugging P=15 and T=1500, finding k,

k=15*1500 = 22500
Next we have to find how many customers would buy a television that costs $2500, so here k=22500 and T=2500, plugging this in the equation we have ,

P=9
So there will be 9 customers that buy a television which costs $2500.
