A relation of a function is only if it relates each element in its domain to only one element in the range
For 46 minutes you can use the computer for $23.
Given that, you can rent time on computers at the local copy centre for a $7 setup charge and an additional $1.75 for every 5 minutes.
We need to find how much time can be rented for $23.
<h3>What is a linear equation?</h3>
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.
Now, every minute charge=1.75/5=$0.35
Let time used be t, so we can write an equation as
7+0.35t=23
Solve the equation for t.
That is, 0.35t=16
⇒t=16/0.35=45.714
⇒t=45.714≈46 minutes
Therefore, for 46 minutes you can use the computer for $23.

Let's assume that the total daily allowance of fat is given, otherwise let's just assign a variable for it.
We can make the formula based on the given data.
Percentage = Total daily allowance of fat given / total intake of fat per day * 100
So, the equation Percentage = Total / 48 * 100 will be used in order to get the percentage of the total amount.
