The number 5 is a real number. is it also a complex number? try to find values of a and b so that 5 = a + b.

The complex representation of 5 = 5 + 0i.  

a =5, b =0

Step-by-step explanation:

Complex Number: Any number of the form (a + ib) is called a complex number. Here a is known as the real part of the complex number and b is known as the imaginary part of the number.

Any real number can be expressed as a complex number , where the imaginary part is 0.

So, the complex representation of 5 = 5 + 0i.  

Here, a = 5 (real part)

and b = 0 (imaginary part)

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
