If it doesn't show, use desmos graphing, it'll help you.
Answer:
13 cm
Step-by-step explanation:
We can get the answer in the following way:
The line graph is unsuitable for her purposes because it does not show adequately the comparison of the expenses.
Line graph is used to show the increase/decrease of a particular variable.
Bar graph is a more adequate format to create a visual representation.
The solution of the given inequality is:
x ≤ 15.24
<h3>
How to solve the inequality?</h3>
We know that the maximum that she can spend on gasoline is the 12% of $400.
That is:
(12%/100%)*$400 = 0.12*$400 = $48
Now, we know that each gallon of gas costs $3.15, then if x is the number of gallons of gas that she buys, we have the inequality:
x*$3.15 ≤ $48
To solve the inequality, we need to divide both sides by $3.15
x ≤ $48/$3.15
x ≤ 15.24
So the maximum number of gallons of gasoline that she can buy is 15 gallons (actually a little more).
