Answer:

  -3x^6 -x^4 +2x^3 -8x +8

Step-by-step explanation:

Use the distributive property 4 times.

  (-3x^3 + 2x - 4)×(x^3 + x - 2)

  = -3x^3(x^3 +x -2) +2x(x^3 +x -2) -4(x^3 +x -2) . . . . once

  = -3x^6 -3x^4 +6x^3 +2x^4 +2x^2 -4x -4x^3 -4x +8 . . . . 3 more times

  = -3x^6 +x^4(-3+2) +x^3(6 -4) +2x^2 +x(-4 -4) +8 . . . . group like terms

  = -3x^6 -x^4 +2x^3 -8x +8

given data

weekly earnings= $375

Commission is 4% of sales.= 0.4

supposing sale is x, and the total earning is y

the expression for the total earning will be

y=375+0.4x

Step two:

for x= 2513, y will be

y=375+0.4(2513)

y=375+1005.2

y=1380.2

<em><u>Hence  her total earnings for the week will be $1380.2</u></em>
