I=prt for t, if i=105, p=700, and r=0.05

I = prt 105 = (700) (0.05) t t = 3

If you would like to solve the equation i = p * r * t for t, you can do this using the following steps:

i = p * r * t

t = i / (p * r)

i = 105

p = 700

r = 0.05

t = i / (p * r) = 105 / (700 * 0.05) = 105 / 35 = 3

The correct result would be t = 3.
