Answer :
In linear equation, $200.62 is his average monthly expense for utilities.
What are a definition and an example of a linear equation?
- An equation with only one variable is referred to as a linear equation in one variable.
- It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value.
- A linear equation in one variable would be 9x + 78 = 18, for instance.
Expenditure in December by Bill = $ 188.31
Expenditure in January by Bill = $192.80
Expenditure in February by Bill = $ 220.75
We have to find the average monthly expenses for Bill's utilities.
We know that,
Average monthly expense for utilities = (Expenditure in December + Expenditure in January + Expenditure in February)/3
Hence, using the data given in the question, we can write,
Average monthly expense for utilities = (188.31 + 192.80 + 220.75)/3
Average monthly expense for utilities = 601.86.01/3 = $200.62
