Answer: $31.99
Step-by-step explanation:
So, it is originally $39.99, so first we convert 20% to a decimal, which is 0.2.
Then we do 39.99 * 0.2 to find how much money was taken off.
39.99 * 0.2 = 7.998, or $8
Now, we do the original dollar amount, $39.99, minus the discount, $8, which equals $31.99.

Answer:
The percentage decrease is 15%.
Step-by-step explanation:
To find the percent decrease of any two numbers, subtract the numbers and divide it by the original.
So in this case:
20-17÷20
= 3÷20
= 0.15
Now convert to a percent.
0.15×100 = 15%
Is the equation like this? x^2 + 25y^2?
If the equation is like that, the answer would be (x-5y)^2 or (x-5y)(x-5y).
how did I get this? Just divide the factors or the get the square root of 25y^2 and it would be 5y. Then just try if it is positive or negative. In this case, it is negative because there is no factor w/ no exponential form. I hopemy answer helped you.
