Five students picked berries in Australia. They worked for 3 days. If they picked for 8 hours each day and together made a total of $960, how much was each person making per hour?

8$ an hour

Step-by-step explanation:

first you do 8×3 then 960÷24 then 40÷5 so in the end you get 8 dollars an hour

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.
