Let, the original amount = x
First discount = x * 0.20 = 0.20x
Amount after first discount = x - 0.20x = 0.80x
Second discount = 0.80x * 0.15 = 0.12x
Amount after second discount = 0.80x - 0.12x = 0.68x
Difference would be: x-0.68x = 0.32x
So, Your Answer would be 32%
Hope this helps!
Remember y ou can do anything to an equation as long as you do it to both sides
get 1x by itself
8x-12=4x+24
add 12 to both sides
8x=4x+36
minus 4x from both sides
4x=36
divide both sides by 4
x=9
Answer:
2 & +2i
Step-by-step explanation:
The two additional roots of the polynomial functions are:
1. 7-5 = 2
2. Irrational root of a polynomial functions are always in pairs, hence
- 2i will have +2i as its pair
the numbers are being divided by 4 so 12/4 =3
next number is 3
