. John Gray bought a basic car for $8,250.00, with options that cost $324.00. There's a 6% sales tax inhis state and a combined $50.00 license and registration fee. What was John's total cost?
A. $9,141.44
B. $14,247.00
C. $9,138.44
D. $10,000.00

Answers

Cost of basic car = $8250
Optional cost = $324
Total cost of basic car and optional items for John= (8250 + 324) dollars
      = 8574 dollars
Then
Percentage of sales tax = 6%
Amount of sales tax = 8574 * (6/100) dollars
   = 514.44 dollars
License and registration fee combined = $50
Then total cost of John in regards to buying the car = 8574 + 514.44 + 50
      = 9138.44 dollars
So option "C" is the correct option in regards to the question given.

You sell pies at a farmers' market for $7.50 each. Five people want to share a pie by splitting the cost equally. How much will each of them need to pay to buy a whole pie together?

Answers

Answer:

Each of them need to pay to buy a whole pie together = $1.50

Step-by-step explanation:

Unit rates defined as the rates are expressed as a quantity of 1, such as 7 feet per second or 9 miles per hour, they are called unit rates.

As per the statement: You sell pies at a farmers' market for $7.50 each.

⇒ Cost of each pie = $7.50

Also, five people want to share a pie by splitting the cost equally.

Number of people = 5

then, by definition of unit rate;

unit rate per people = $(Cost of whole pie)/(Number of people) = (7.50)/(5) = \$1.50$

Therefore, $1.50 will each of them need to pay to buy a whole pie together.
