Question

How to solve both 62 and 63

Answer 1

You just put the number in for m with the formula you have. 12 months will give you T=2800.4*12 T will be 62) $33604.80 and with 36 months T=2800.4*36 will be 63) $100814.40

Answer 2

62.) T = 2800.4 * m.......in 12 months...so sub in 12 for m
        T = 2800.4 * 12
        T = $ 33,604.80 <==

63) after 36 months...so sub in 36 for m
      T = 2800.4 * 36
      T = $ 100,814.40 <==
