We want our exponential function to look like
y = ab^x.
Let a = the initial y-value.
Our initial value is the first number given for f(x). So, a = 3.
Let b = the number that is needed to go from 3 to 6 to 12 to 24 to 48.
We find b by division.
So, b = the next number divided by the previous.
So, b = 6/3 = 2.
We now plug in our values into the general formula above.
y = ab^x
Answer: y = (3)(2)^x
Answer:
Company A has a greater daily rate
Step-by-step explanation:
Given
Company A


Company B

Required
Determine the company with greater rate
Simplify the expression of company B



In a linear function:

m represents the rates.
This implies that the rate of company B is:

and the rate of company A is

By comparison:
Company A has a greater daily rate
3/5 > 7/10
Reasons:
3/5 = 6/10 because 3/5 x 2/2 = 6 / 10
6 > 7 so 6/10 > 7/10
Therefore: 3/5 >7/10
So if she got them at 30% off that means
$63 = 70%
divide both sides by 70 to get 1%
$0.90 = 1%
multiply by 100 to get full price
$90 = 100%
original price was $90
