Answer:
60 miles.
Step-by-step explanation:
Given:
We rent a car for the day and are offered two payment options.
With option A we pay $25 flat rate plus $0.15 per mile.
With option B we pay a $10 flat rate plus $0.40 per mile.
Question asked:
For what amount of miles would the cost of option A be equal to option B ?
Solution:
<u>Let amount of miles for which the cost of option A be equal to option B = </u><u />
For option A, we pay =
For option B, we pay =
Now, to find amount of miles for which the cost of option A be equal to option B, we will equalize the equation to find the value of
By subtracting both sides by 10
By subtracting both sides by
By dividing both sides by
Therefore, for 60 miles, the cost of option A will be equal to option B.
Answer:
2%
Step-by-step explanation:
Let x be the first number
It increases by 70 %
The new number is
m = x+ .70x
= 1.7x
Let y be the second number
It decreases by 40 %
The new number is
n =y - .40 y
= .6y
The product of the original numbers is xy
The product of the new number is
mn = (1.7x * .6y) = 1.02xy
The new number is larger than the old number so it is an increase.
Percent increase is new - original divided by original times 100%
Percent increase = (1.02 xy - xy)
----------------- * 100%
xy
= .02 xy
------- * 100 %
xy
= .02 * 100 %
= 2%
Step-by-step explanation:
<u>So the domain of f(x) := tanx is all real numbers except x = π 2 + kπ, k an integer.</u>
I would say that d is not equivalent to that equation
