The total cost of the item at the value of $25 and a tax of 7% is $26.75
<h3>Total Cost </h3>
Given Data
We have the given expression to find the total cost which is
Total = c + 0.07c
Substituting our given data into the expression we have
Total = 25 + 0.07*25
Total = 25 + 1.75
Total = $26.75

F ( 6 ) = -16·6²+32·6+90= -576 + 192 + 90 = -294
f ( 4 ) = -16· 4³+32·4+90=-256+128+90= -38
The average rate of change: [f(t2)-f(t1)]/ t2-t1=
[-294-(-38)] / (6-4) = -256 : 2 = -128 feet/s
In order to solve this you would need to know the original, or sale price of the apples themselves. Do you have this data?
I think there are no solutions - firstly, you can't add two numbers and get one solution, and add the same two numbers up again and get a different solution!
also, if you plot the two lines on a graph they never intersect, showing there are no values of x or y that satisfy both equations.
The equation of the line is x=4
