The <u>possible rational zeros</u> of <u>polynomial function</u> 
could be only among the <u>divisors</u> of the <u>free term</u> of this polynomial function.
The free term is 20 and the divisors of 20 are:
Answer: correct choice is C
The equation governiong this relationship is y = kx. Since y = 25 when x = 60,
25 = 60k, and k=(5/12). Thus, the equation is y = (5/12)x.
If y = 30, then 30 = (5/12)x. Mult. both sides by 12/5 to obtain the value of x:
(12/5)(30) = 360/5 = 72
The factors are 1 and 47, since 47 is a prime number.
If it is 20% off, then ur actually paying 80%
so an equivalent expression would be 0.80p
