The answer I got is $24 7/8. Hope this helps
Answer:
B
Step-by-step explanation:
First, let's rearrange the given equation into something more recognizable. If we add 13 to both sides, we now have the polynomial
. We can now use the quadratic formula to solve.
Remember that the quadratic formula is

Substitute the numbers from the equation into the formula.

Simplify:


Here, I'm going to assume that there was a mistype in option B because if we divide out the 2 we end up with
.

If d is days and m is is miles
rate= 39d + 0.47m
Here we use altitude rule which states that
Ratio of part of hypotenuse and height= ratio of height and remaining part of hypotenuse .
So here parts of hypotenuses are r and s and h is the hypotenuse. SO we will get

Correct option is s.
