The greatest common factor (or GCF) is, as the name says, the greatest factor a set of numbers have in common. We can find this by listing out all the possible factors (multiples) of each number:
For 28:
<u>1</u>, <u>2</u>, 4, <u>7</u>, 14, 28
For 42
<u>1</u>, <u>2</u>, 3, 6, <u>7</u>, 21, 42
<em>(note you don't need to list out all the factors, I just did it for visual purposes)</em>
As you can see, 28 and 42 have 3 factors in common, with 7 being the greatest.
Therefore, the answer would be C: the GCF is 7.

Answer:
c
Step-by-step explanation:
let's say the original price is "x", so that'd be the 100%.
and we know that is discounted by 30%, 100% - 30% = 70%, we know the discounted price is 206.50, so namely 206.50 is the 70% then.
if 206.50 is 70% of "x", what is "x"?
Step-by-step explanation:
100% = 4.25
1% = 100%/100 = 4.25/100 = 0.0425
how many % are 3.4 ?
we find this by calculating how often 1% (0.0425) fits into 3.4.
3.4 / 0.0425 = 80 %
