If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.

Calculate the rent of a decreasing annuity at 8% interest compounded quarterly with payments made every quarter-year for 7 years
Papessa [141]
The general Formula for a decreasing Annuity is:
P = ( \frac{(1+i)^n -1}{i (1+i)^n}) R
For this example we have:
P = 78,000
n = 7*4 = 28
i = 8%/4 = 2% = 0.02

After substituting you can find value for R, rent.
