you just have to subtract rope B from rope A and you’ll get your answer :)
A=p(1+i/m)^mn
A=1,200×(1+0.03÷2)^(2×7)
A=1,478.11
Subtract.
596 3/5 - (-81.8) [81.8 is below sea level so it is negative]
566.6 + 81.8 [Convert to decimal and distribute negative]
= 678.4 feet
If you separate the numbers 58 to 50 and 8 you get the values for both.
