### \_getMintAmountOut

```solidity
function _getMintAmountOut(
    uint256 amountIn
) internal returns (uint256 amountChiOut)
```

helper function to get mint amount out based on current market prices

will revert if price is outside of bounds and bounded PSM is being used

| ---------- | ------- | ----------- |
| `amountIn` | uint256 |             |

### \_getRedeemAmountOut

```solidity
function _getRedeemAmountOut(
    uint256 amountChiIn
) internal returns (uint256 amountTokenOut)
```

helper function to get redeem amount out based on current market prices

will revert if price is outside of bounds and bounded PSM is being used

#### Parameters

| Name          | Type    | Description |
| ------------- | ------- | ----------- |
| `amountChiIn` | uint256 |             |
