Which situation is best represented by the following equation? 20h+40=480
The equation 20h + 40 = 480 represents a situation where someone is earning $20 per hour, and they have already earned $40. The equation is used to find out how many hours (represented by "h") the person needs to work in order to reach a total earnings of $480.
The given equation, 20h + 40 = 480, can be solved to find the value of 'h' that satisfies the equation.
To solve it, we can start by isolating the variable 'h'.
First, let's subtract 40 from both sides of the equation to get rid of the constant term:
20h + 40 - 40 = 480 - 40
Simplifying further:
20h = 440
Next, divide both sides of the equation by 20 to isolate 'h':
20h/20 = 440/20
Simplifying:
h = 22
So, the value of 'h' that satisfies the equation is 22.
To understand which situation is best represented by this equation, we need to interpret the equation in the context of the problem. The equation can be written as "20h + 40 = 480."
The equation represents a situation where '20h' (which represents a certain quantity) added to 40 equals 480. In other words, if you have 20 times some number 'h' and add 40 to it, the result is 480.
To determine the specific situation, we need more information about what 'h' represents.
The given equation is 20h + 40 = 480.
This equation can be used to represent a situation where someone is earning $20 per hour.
The initial amount (40) indicates that they have already earned $40.
The total earnings after h hours can be calculated by multiplying the hourly rate ($20) by the number of hours (h) and adding the initial amount ($40).
The equation is set equal to 480, which represents the desired total earnings.
