Answer:
As per the given statement:
Original price of a set of feeding bowls for dogs = $9.25
Increased Price = $11.10
To find the percentage increase.
Substitute the given values we have;
Simplify:
therefore, the increased percentage was 120%
The first thing we must do for this case is to define variables.
We have then:
P: pressure
A: Area of the sole of the shoe
Since the variation is inverse, we have an equation of the form:
We must find the value of k.
For this, we use the following data:
when the shoes have a sole area of 40 in ^ 2 The pressure is 4 lbs / in ^ 2
Substituting values we have:
From here, let's clear k:
Then, the equation is:
