Answer:
1/2 is equivalent to 50%
Step-by-step explanation:
In order to convert a fraction to a percentage you divide the numerator (Top number of a fraction) by the denominator (Bottom number of a fraction), multiply by 100, and add a percentage sign.
So lets try that with our first answer option A) 1/2:
1 divided by 2 = 0.5
0.5 x 100 = 50
50%
So we know that 1/2 is equivalent to 50%
The solution of the given inequality is:
x ≤ 15.24

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).
