What is the gcf of these monomials?

There's a 30 coefficient on the first and no coefficient (i.e. a 1) on the second.  So the GCF of the constant part is GCF(30,1)=1.

Similarly, because both have as a factor.

because both have as a factor.

Now that we see how the bits work it's not too hard to read these off:

step-by-step explanation:

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
