Discounts are used to reduce the original price of an item.
David will pay $25 and 92 cents for an item of $32, before tax
The discount (d) is given as:
The price (p) of the item is given as:
So, the amount (A) paid before tax is calculated using:
Substitute known values
Express percentage as decimal
Subtract 0.19 from 1
Multiply 32 and 0.81
Hence, David will pay $25 and 92 cents for an item of $32, before tax

Answer:
h(x) = -x^2 - 1
Step-by-step explanation:
well y, h(x), f(x), n(x), or any other something of x is all the same thing y.
So if f(x) is -x^2 - 1,
Then h(x) is also -x^2 - 1
Answer:
648
Step-by-step explanation:
Running this in Python, with the code as follows,
import math
cur_numbers = [0] * 3
num = 0
for i in range(100, 1000):
cur_numbers[2] = i % 10
i = math.floor(i/10)
cur_numbers[1] = i % 10
i = math.floor(i/10)
cur_numbers[0] = i % 10
if(len(set(cur_numbers)) == 3):
num += 1
print(cur_numbers)
print(num), we get 648 as our answer.
Another way to solve this is as follows:
There are 9 possibilities for the hundreds digit (1-9). Then, there are 10 possibilities for the tens digit, but we subtract 1 because it can't be the 1 same digit as the hundreds digit. For the ones digit, there are 10 possibilities, but we subtract 1 because it can't be the same as the hundreds digit and another 1 because it can't be the same as the tens digit. Multiplying these out, we have
9 possibilities for the hundreds digit x 9 possibilities for the tens digit x 8 possibilities for the ones digit = 648
Hello there!
Answer:
You can also round up to the nearest tenths is 15.1 to 15.0 and its going to be stay.
Step-by-step explanation:
First you had to switch sides of equation form.
Then you add by 0.3 from both sides of equation form.
And finally, simplify by equation. You can also cross out by -0.3+0.3 and it gave us equal to zero. Then you add 14.8+0.3 and it equal to 15.1. You had to used their variable and its should be the right answer.
Hope this helps!
