The total cost of the dinner is $176.20.
<h3>What is the total cost of the dinner?</h3>
The total cost of the dinner is the sum of the bill for the dinner, the tax and the tip.
Total cost = tip + bill of the dinner + tip
Tax = 0.08 x 140 = $11.20
Total cost = $140 + $25 + $11.20 = $176.20

Hey there! I'm happy to help!
The distributive property is when you multiply a number outside the parentheses by each term inside. We see this demonstrated in answer D) 6n-6=6(n-1).
6(n-1) can be undistributed. 6(n)=6n and 6(-1)=-6, giving us 6n-6, which is still equal to 6(n-1).
Have a wonderful day! :D
Answer:
Step-by-step explanation:
Given
x 2 4 6 8
y 1 2 3 4
Required
Determine the constant of proportionality (k)
The relationship between x and y is:
When y = 1, x = 2;
So, we have:
Make k the subject
Hence, the constant of proportionality is 1/2
Y = mx + b
First equation 1 = m(4) + b, bring everything to one side m(4) + b - 1 = 0
Second equation 7 = m(5) + b, bring everything to one side m(5) + b - 7 = 0
Set them equal to each other,
m(4) + b - 1 = m(5) + b - 7
If you bring the b over to the left hand side it becomes
m(4) + b - b - 1 = m(5) - 7
m(4) - 1 = m(5) - 7
Solve for m
6 = m
Plug m = 6 into either equation from the beginning,
m(4) + b - 1 = 0
6(4) + b - 1 = 0
24 + b - 1 = 0
b = -23
Knowing m and b we can now make an equation
y = mx + b
y = 6x -23 Final answer
