Ronan Osborne · Answer 1

y (t) = 240,000 x (1 + 0.097) ∧t

Step-by-step explanation:

y (1) = 240,000 x (1 + 0.097)

y (2) = 240,000 x (1 + 0.097) x (1 + 0.097) = 240,000 x (1 + 0.097) ²

y (3) = 240,000 x (1 + 0.097) x (1 + 0.097) x (1 + 0.097) = 240,000 x (1 + 0.097) ³

y (t) = 240,000 x (1 + 0.097) ∧t
