The total cost of an order of shirts from a company consists of the cost of each shirt plus a one-time design fee. The cost of
each shirt is the same regardless of how many shirts are
ordered.
The company provides the following examples to customers to
help them estimate the total cost of an order of shirts:
50 shirts cost $349.50
500 shirts cost $2370
.
Part A
Based on the examples, what is the cost of each shirt, not
including the one-time design fee?

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!

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
