The total costs incurred in 2018 at various output levels in a factory have been measured as follows: Output
(units)
26
30
33
44
48
50
Total Cost $
6566
6510
6800
6985
7380
7310
When output is 80 units or more, another factory unit must be rented and fixed costs therefore increase by 100%.
Variable cost per unit is forecast to rise by 10% in 2019.
What is the estimated total cost of producing 100 units in 2019?

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!

sorry but i cant draw that
