Final answer:
To find the number, set up an equation using the given information and solve for the variable.
Step-by-step explanation:
To find the number, we need to set up an equation based on the information given. Let's represent the unknown number as x. According to the question, the triple of the number (3x) plus 120 is equal to 480. So, we can write the equation as 3x + 120 = 480.
To solve for x, we subtract 120 from both sides of the equation: 3x = 360. Next, divide both sides by 3: x = 120.
Therefore, the number is 120.
