soln::
900 dollars is the Fixed Amount which she will get every month

plus a 10% commission on sales over 1000
as she sell "r" dollars of merchandise
and "r">1000

therefore
her net commission would be
= 900 + 10%(1000-r)
=800+0.1r
ans

so Option A is the anser

Hello!

Fixed salary = \$900

Variable salary = 10 % of sales above \$ 1000.

As in question , it is given r is greater than \$ 1000.
She will get 10 percent of r- 1000 as variable salary or performance pay.
So her total salary = fixed salary + variable salary or performance pay.
= 900 + 10%(r-1000)
= 900 + 0.1r -100
= 800+ 0.1r.

(B) 800 - 0.1r

(C) 900 + r

(D) 900 - 0.1r

(E) 810 + 0.1r

We can create the expression:

900 + 0.1(r - 1000) = 900 + 0.1r - 100 = 800 + 0.1r
