Leslye is a salesperson at a home improvement center. she is paid a monthly commission that is 7.5% of her first $1,000 in sales and 12% of the balance of her sales. today she earned $517. what was the total value of merchandise sold?

She sold for $4683.33

Step-by-step explanation:

For a sales of $1000 she is paid 7.5% which is equivalent to $75.

Since she earned $517 , her total sales was more than $1000.

Let she had a sales of $(1000+x).

Then her commission would be $75 + 12% of $x .

But her total commission was $517.

Then commission from sales after she sold for $1000 = $(517 - 75)

                                         = $442

This is also equal to 12% of x.

x = $3683.33

Hence she sold for $4683.33

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
