Aclerk earns $7.50 an hr, plus a commission of 5% of sales. if she works a 40 hr week and sells $6300 worth of goods, what does she earn that week?

Givens

Work week = 40 hours

Paid 7.50 an hour.

Sells 6300 worth of goods.

Equation

Take home pay = Sales * 5% + 7.50 * number of hours.

Sub and Solve

Take home pay = 6300 * 5% + 7.50 * 40

Take home pay = 6300 * 5/100 + 7.50 * 40

Take home pay = 315 + 300

Take home pay = 615 dollars.

Answer 615 <<<<

it's

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.
