Michael is 4 times older than brandon and is also 27 years older than brandon. how old is brandon?

Brandson is 9 years old and Micheal is 36 years old

Step-by-step explanation:

Let the age of Brandson be x years

then the age of Micheal be y years

According to the given condition

y=4x1

y= x+272

From 1:                    x= y/4 3

Putting 3 in 2

y = y/4 +27

y= y+  108/4

4y= y +108

4y - y= 108

3y= 108

y = 108/3

y= 364

Putting 4 in 1

36= 4x

x= 36/4= 95

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

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
