Answer:

$b=\dfrac{W}{Y}-A$

Step-by-step explanation:

As with any "solve for ..." problem, you undo what is done to the variable of interest. Here, what is done is ...

You "undo" these operations in reverse order (from the bottom of the list up). To undo multiplication, you multiply by the reciprocal:

$W\dfrac{1}{Y}=Y(b+A)\dfrac{1}{Y}=b+A$

To undo the addition of A, add the opposite of A:

$\dfrac{W}{Y}-A=b+A-A\\\\b=\dfrac{W}{Y}-A$

First we should find the percent that this number of miles are currently at:
20n = 11
n = 11/20
n = 0.55
1 - 0.55 = 0.45
