Answer: Answer is D, if I'm not mistaking
Step-by-step explanation:
sorry if im wrong.
Start by decomposing the number inside the root into primes
Then group the terms into cubes if possible
rewrite the root
then cancel the terms that are cubes and bring them out of the root
C.) 30 since they both have 5's just take them out then subtract 50 and 20 *but make sure u take out the decimal though* so after u subtract u will get 30 then line it up and put the decimal back then it will be .30
so, the interest earned then will be A - 3500.
