Let the original price be x . And the stores are offereing 20% discount. It means , we need to pay only 80 percent.
And it is given that the discount prices is 16.80. That is
0.8x = 16.80
Now we need to get rid of 0.8.
And for that, we divide both sides by0.8,
x =21
So the original price is $21 .
108x/56x Hope that helps.
(2k² + 5k - 6)(3k - 1)
(6k³ - 2k² + 15k² - 5k - 18k + 6)
6k² + 13k² - 23k + 6
Use the FOIL method to simplify the problem.
(FOIL stands for first outer, inner, last)
<h3>4 times a number increased by 3.</h3>
When we have a number that appears
right before a variable, it means multiplication.
So 4n means the same thing as 4 times a number.
Remember, n is a variable which is just a
letter that represents any number.
Since we are adding 3 to 4n, we can say
4 times a number increased by 3.
So 4n + 3 can be written as 4 times a number increased by 3.
