Question

To estimate your average monthly salary, divide your yearly salary by the number of months in a year. Write and solve an equation to determine your yearly salary when your average monthly salary is $4,559.

Answer 1

yearly salary = $54,708

Explanation:

Let monthly salary be x

Let yearly salary be y

Let number of months be n

To estimate your average monthly salary, divide your yearly salary by the number of months in a year. This can be written as

x = y divided by n

`x = (y)/(n)`

Therefore, writing an equation to determine yearly salary is the same as making the yearly salary 'y' the subject of the formula above:

`x = (y)/(n)\\cross-multiplying\\n\ *\ x= y\\y\ =\ nx`

where y = ???

x = $4,559

n = 12 months

`y = 4,559\ *\ 12 \\= \$\ 54,708`

Therefore yearly salary = $54,708
