Let $S = G(t)$ be a function which will calculate the salary $S\text{,}$ in dollars, for working $t$ hours per month.

1. Choose the correct notation for the following statement:
   The salary is $\$2900$ for working $160$ hours per month.
   $G(2900) = 160$
   $G(160) = 2900$
2. Choose the correct notation for the following statement:
   If you work $90$ hours per month, your salary will be $\$1500\text{.}$
   $G^{-1}(1500) = 90$
   $G^{-1}(90) = 1500$
