Answer:
The original price is $18
Step-by-step explanation:
First, turn the percent into a fraction by dividing by 100.
20% to 0.2
Remember that the original price(x) multiplied by 1- the discount(0.2) equals the sale price(14.4)
(1-0.2)x=14.4
0.8x=14.4
Divide both sides by 0.8 to get:
x=18
I think the answer is y +z= x
Standard form of a complex number is <em>a + bi</em> This can be achieved by combining like terms. So
-2 + 10 + -2i -4i
8 - 6i
So 2 is our answer: 8 - 6i
