Restaurants frequently add an 18% tip on the pre-tax bill when the party is 8 people or more. The tax is calculated based on the bill before the tip is included. Last night, friends went out to dinner and decided to split the bill evenly. If the bill without tax or tip was $ and the tax was %, how much did each person owe?
The money each person owes at restaurants for dinner is $1.41.
What is tax?In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.
Given that, Restaurants frequently add an 18% tip on the pre-tax bill when the party is 8 people or more.
The first step is to determine the total cost of the dinner. The total cost includes the cost of the dinner, tip and tax.
Total cost = Cost of the dinner + Tax + Tip
Tax = Cost of the meal x Percentage tax
Tax = $114.46 x 5%
Tax = $114.46 x 0.05 = $5.723
Tip = Percentage tip x Cost of the diner
Tip = 18% x $114.46
Tip = 0.18 x $114.46
Tip = $20.60
Total cost = $114.46 + $20.60 + $5.72 = $140.78
Amount each person owes = Total cost of the meal / Number of people
Amount each person owes = $140.78/10 = $1.41
Therefore, the money each person owes at restaurants for dinner is $1.41.

Which is the product of 15 and 5/12 ?
Answer:
6 1/4
Step-by-step explanation:
15 x 5/12 = 15 x 5/12 = 75/12
75/12= 6 3/12 = 6 1/4
The product of 15 and 5/12 is 25/4.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
Two numbers 15 and 5/12.
The product of 15 and 5/12:
Multiplying both numbers,
15 x 5/12,
= (15 x 5)/12
= 75/12
Simplifying further,
= 25/4
Here, 25/4 can not be simplified further.
Because the GCF of 25 and 4 is 1.
Therefore, the value is 25/4.

Answer: 6) x= 17 Same side interior angles sum to 180.
7) x= 3 Alternate exterior angles are equal.
8) x= 35 Corresponding angles are equal.
9) x= 12 Alternate interior angles are equal
Step-by-step explanation:
6) x= Same side interior angles sum to 180.
53+(8x-9)= 180
44+8x= 180
Subtract 44 from both sides
8x= 136
Divide both sides by 8
X = 17
7) x= Alternate exterior angles are equal. 15x+29= 26x-4
Subtract 15x from both sides
29= 11x-4
Add 4 to both sides
33= 11x
Divide both sides by 11
X=3
8) x= Corresponding angles are equal.
4x+7= 6x-63
Subtract 4x from both sides
7 = 2x -63
Add 63 to both sides
70= 2x
Divide both sides by 2
X= 35
9) x= Alternate interior angles are equal
9x+37= 14x-23
Subtract 9 x from both sides
37= 5x -23
Add 23 to both sides
60= 5x
Divide both sides by 5
12=x
