I can't figure out a factor for this but graphing it shows x = -2 and +1 as real roots.
First convert 22 to decimal form. You do this by dividing the percent by 100.
22 / 100 = .22
Then multiply the dollar amount by the percentage in decimal form.
$45 * .22 = $9.9
So 22% of $45 is $9.9.
Then you subtract $9.9 from $45.
$45 - $9.9 = $35.1
Answer:
-2x = -60
Isolate x and simplify.
2x = 60
x = 30
Straight vertical line through x=30.
So, let's look at the problem once again.
8%, or 8/100 of the bag were green jelly beans.
Let's see what we can do to find out a number of other jelly beans, not including the green ones.
We know that 92% of jelly-beans are not green.
92% is 11.5 times more than 8%
(92/8)
24 (or 8%) times 11.5 = 276
276 - number of jelly beans that are not green.
276 plus 24 = 300.
Answer: 300 jelly beans were in one bag.
