It is -6.

Step-by-step explanation:

7 + 12 is 19

The answer you are looking for is b = -6.

There are 2 ways to find this. You could use...

Add together 7 and 12 to get 19, then subtract 19 from both sides to get b = -6. OR...
Subtract 12 from both sides to get b + 7 = 1, then subtract 7 from both sides to get b = -6.

Either way, you will get the same answer of b = -6. One method is just longer than the other. I hope this helps!

Now to put the value of interest in the given formula,

We need the value of r.

r = $\frac{r \%}{100} = \frac{4.8}{100} = 0.048$

Hence, the value of r to be out in the given formula is r = 0.048.
