The function Y=4.75+2.20(X-1) can be used to determine the cost in dollars for a taxi ride in Houston, TX. What is the rate of change of the cost in dollars with respect to the number of miles?

Answers

Answer:

2.20 dollars/mile

Step-by-step explanation:

Given the function:

y = 4.75 + 2.20(x-1)

Before we get the rate of change of the cost, we need to write the expression in the form y = mx+c where;

m is the rate of change of the cost

From the function given:

y = 4.75 + 2.20(x-1)

Open the parenthesis

y = 4.75 + 2.20x -2.20

y = 2.20x + 2.55

On comparing with the standard

m = 2.20

Hence the rate of change of the cost in dollars with respect to the number of miles is 2.20 dollars/mile

39.5-29.5 = 10$ for initial for group

49-29.5 = 19.5 perhour for individual

The sum of two numbers is 12 times larger than one set and 29 times larger than the other set. What are those numbers and what is their sum?

Answers

Answer:

Step-by-step explanation:

This is a very impossible question to solve because we are not given any idea what both sets are, or at least either of them is. And thus, even if we write down an inequality equation, I doesn't solve the question, it rather makes one ask more questions.

If the two numbers are, say, a and b, and the first set is x, while the second set is y then we have an inequality in the sense that

a + b = 12x

a + b = 29y

How to proceed with no idea what x or y is, is well, not possible

Suppose a friend tells you she paid a total of $20,500 for a car, and you’d like to know the car’s list price (the price before taxes) so that you can compare prices at various dealers. Find the list price of the car if your friend bought the car in:

Roswell, where the sales tax is 6.5%

Answers

Given :

Total amount paid for the car is, A = $20,500.

Sales tax is 6.5%.

To Find :

The list price i.e. price without tax.

Solution :

Let, list price is P.

P = A - 0.65A

P = A( 1 - 0.65 )

P = 20500×( 1 - 0.065 )

P = $19167.5

Therefore, the list price of car is $19167.5 .
