Exponential growth/decay formula

x(t) = x₀ × (1 + r)^t

x(t) is the value at time t.

x₀ is the initial value at time t=0.

r is the growth rate when r>0 or decay rate when r<0, in percent.

t is the time in discrete intervals and selected time units.

x₀ = 50

r = 4% = 0.04

t = 90 hours

x(t) = x₀ × (1 + r)^t = 50×(1+0.04)⁹⁰ = 1706
