Let a = Imani's weekly allownace
She spent half of her allowance, so she has half it left = a/2. She got $4 more from washing the car, so she has a/2 + 4 dollars which totals $12:
a/2 + $4 = $12
a/2 = $8

Answer:
81mm
Step-by-step explanation:
the number of steps is small enough that we can simply list out each step
let the time elapsed be t and the original length be L ( = 1 mm)
when t = 0, L = 1mm
when t = 10, L = 3mm
when t = 20, L = 3 x 3 = 9mm
when t = 30, L = 9 x 3 = 27mm
when t = 40, L = 27 x 3 = 81mm
