According to the problem, y = f(x) = 2x
Here the value of x = 2.
We have to put the value of x in place of x in 2x to calculate the actual value of 2x.
Therefore, after putting the value of x in 2x we get 2x = 2 x 2 = 4
This means the value of 2x is 4. This is because we have included the given value of x to get the value of 2x.
Again the value of f(x) = 2x.
Therefore, the value of f(x) = 2x = 4.
2000 / 4 = 500
500 + 5% = 25
1500 + 1%= 15
Total cash back = 40$
First you figure out that the ratio 7:4 is 1.75
Then you do this problem 28 divided by 1.75=16
And 28:16 is the same as 7:4
Now all you do is add 28+16=44
Answer:
your answer will end up being x=-5
