The subtotal of a dinner bill is dd dollars. There is an 8% dine-in tax, and the customer would like to leave an 18% gratuity based on the subtotal amount. Write an expression that represents the total amount the customer spends on dinner, including the tax and gratuity.

1.26d

Step-by-step explanation:

Given that :

Subtotal = d

Dime - in tax = 8%

Gratuity = 18% of subtotal

Total amount spent on dinner :

Gratuity = 18% of d

Gratuity = 0.18 * d = 0.18d

Dine - in tax : = 8% of dinner bill

Dine - in tax = 0.08d

Total cost of dinner :

Dinner bill + dine - in tax + Gratuity

d + 0.08d + 0.18d

= 1.26d

Total amount spent on dinner = 1.26d

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
