$2.39 is 100%
$x is 7%
2.39 x 7 = 16,73
16,73/100 = 0,17
the total cost is $2,56
-7z^7(-19z^7) = (-7 x -19) x z^(7 + 7) = 133z^14
see the attached figure to better understand the problem
we have that

Step 1
<u>Find the value of AC</u>
we know that
in the right triangle ABC

substitute the values in the formula

Step 2
<u>Find the value of BC</u>
we know that
in the right triangle ABC
Applying the Pythagorean Theorem

substitute the values

Step 3
<u>Find the value of BD</u>
we know that
in the right triangle BCD
Applying the Pythagorean Theorem

substitute the values


therefore
<u>the answer is</u>
the length of BD is 11.93 units
