The total cost of this television at the store will be $ 193.30. Then the correct option is A.
The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.
At an electronics store, a $165 television is marked up 110%.
Trevor purchases the TV and must pay 6.5% sales tax.
Then the total cost of this television at the store will be
Total cost of TV = $ 165 x 1.10 x 1.065
Total cost of TV = $ 193.30
Thus, the correct option is A.

The average rate of change of function is 72.
SOLUTION:
Given that, we have to find the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4
Use the slope formula to find the average rate of change:
To simplify this, we need to find values of f ( 4 ) and f ( 2 ) :
Answer:
Step-by-step explanation:
If it's parallel, that means it has the same slope: -1/5.
Use point-slope form to write the equation:
y - 4 = -1/5 (x - 7)
If you wish to write in point-intercept form:
y - 4 = -1/5 x + 7/5
y = -1/5 x + 27/5
If two lines are parallel, it means that they will have the same gradient:
And remember, the equation of a line is y = mx +c
-----------------------------------
So we know that the equation of the parallel line is:
y = - x + c through point (7, 4)
All we need to do now is to work out what c is
Note: at point (7,4) x = 7 , and y = 4.
So to work out c, we substitute in the values of x and y, and solve:
y = - x + c
4 = - * 7 + c
4 = -1.4 + c
5.4 = c
----------------------------------
Finally, we just put the value of c back into the original equation
y = - x + 5.4
------------------------------------------
Answer:
The equation of the a line parallel to y = - x + 3 through point (7,4)
is: y = - x + 5.4
