Question

A sales clerk's daily earnings include $125 per day plus commission equal to x percent of his daily sales.

Entar an equation that can be used to find the commission percentage (x), if the clerk's daily sales are $1375 and his total earnings for that day are $180.

Answer 1

The commission percentage is
`x=2.18\%`

Explanation:

we know that

The commission percentage (x) multiplied by Clerk's daily sales of $1,375 plus $150 must be equal to $180

so

The linear equation that represent this situation is

`1,375x+150=180`

Solve for x

`1,375x=180-150`

`1,375x=30`

`x=0.0218`

Convert to percentage

`x=0.0218*100=2.18\%`
