Lois is paid 245 per week plus a 12% commission on all sales. his gross pay was $1320 last week. what was her amount of total sales?

We know Lois's gross pay is

... gross pay = $245 + 12%×sales

And we are given gross pay. So, we can substitute the given information and solve for sales.

... $1320 = $245 + 0.12×sales

... ($1320 -245) = 0.12×sales

... sales = $1075/0.12 = $8958.33

Lois's amount of total sales last week was $8958.33.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
