1. In a bag of Skittles, 35% of the candies are orange. How many orange Skittles are in the bag? 2. Dan uses a coupon at CVS that saves him 20%. On his receipt, he sees that he saved $3. How much was his bill before he used the coupon?

For the second question the ANSWER is: 15

Step-by-step explanation:

Before he saves 20% he had to pay 15$.

1) If the 20 percent makes her save 3$ than we have to multiply 3$ by 5 so the percentage would be 100

2) 5*3 = 15$

- Checking -

1) We do 100/15 so we can find the one percent.

2) The one percent is 0.15

3) We do 0.15 * 20 so we can find the 20 percent of the total money.

4) The answer is equals 3 which is correct.

Sorry, because I know this subject I did this solving reverse but I hope you got the idea.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
