Karl is comparing the interest rates for accounts at two different banks. He will deposit $600 into an account and will not make any additional deposits or withdrawals. Bank Q offers 1% interest compounded annually. Bank R offers 1.5% simple interest. Which statement about these accounts at the end of 2 years is true?

Step-by-step explanation:

The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.

Case Q:  i = p(0.01)(2) = 0.02p

Case R:  i = p(0.015)(2) = 0.03p

In case R, the interest earned is 0.03p, which is 1.5 times the interest earned in case Q.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
