Question

The monthly salary of a show room attendant is the sum of a fixed

salary of $600 plus 8% of all monthly sales. What should the monthly
sales be so that her monthly salary reaches $1,800?

Answer 1

Monthly sales = $15000

Explanation:

Let x be the monthly sale.

Given:

The monthly salary of a show room attendant is the sum of a fixed salary of $600 plus 8% of all monthly sales.

8% of monthly sale =
`(8)/(100)* mothly\ sale`

8% of monthly sale =
`(8)/(100)* x`

So, the monthly salary of attendant is.

`Monthly\ salary = 600+8\ percent \ of\ monthly\ sales`

`Monthly\ salary = 600+(8)/(100)* x`

Monthly salary is given.

`1800 = 600+(8)/(100)* x`

`1800 - 600 = (8)/(100)* x`

`1200 = (8)/(100)* x`

`x=(1200* 100)/(8)`

`x=(120000)/(8)`

`x=15000`

Therefore, the monthly sale is $15000
