Answer:
x = ±√37/9
Step-by-step explanation:
x² = 37/81
√(x²) = √(37/81)
x = ± √(37)/√(81)
x = ± √37/9
For this case we have the following variables:
x: number of months
f (x): number of caps sold
The function that models the problem is given by:

By the time the store sells 64 caps we have:

From here, we clear the number of months:

Answer:
the store sells 64 caps in 3 monts
