Answer:
$11,625.80
Step-by-step explanation:
The equation is 3400(1.075)^17
Step 1: Assign variable for the unknown that you need to find.

Step 2: List the given details
Distance between you and your friend is 12 miles. It means the total distance traveled by you by walk and your friend using bicycle when both travel towards each other to meet in 't' hours
Equation 1:

Your Walking rate and your friends Cycling rate is given below:

Step 3: Set up an equation using the relationship between distance, time and rate.


Substituting the above in equation 1

Distance traveled by you by walking from home and distance travelled by your friend in cycle in 0.8 hours is given below:

-- If FE is the longest side in the right triangle, then
the length of the missing side is 22.956... (rounded).
-- If FE is not the longest side in the right triangle,
then the length of the missing side is 25 (exactly).
I hate rounding.
Let's call the diagonal x. It's the hypotenuse of the right triangle whose legs are the rectangle sides.
According to the problem we have a length x-4 and a width x-5 and an area
82 = (x-4)(x-5)
82 = x^2 - 9x + 20
0 = x^2 - 9x - 62
That one doesn't seem to factor so we go to the quadratic formula

Only the positive value makes any sense for this problem, so we conclude

That's the exact answer. Did I mention I hate rounding? That's about
x = 13.6 meters
Answer: 13.6
----------
It's not clear to me this problem is consistent. By the Pythagorean Theorem the diagonal satisfies

which works out to

That's not consistent with the first answer; this problem really has no solution. Tell your teacher to get better material.
He can fill 6 boxes. 48 / 7 = 6R6.
I interpreted the remainder by removing the remainder to get the answer.
