Lesson 4 challenge I keep getting the wrong answer --> Can't solve it

[lamtrinh259]

So for lesson 4 challenge NFT, I thought that the correct answer should be the live feed price as of the date (Jul 1st 2023) of when I'm submitting it. I got the price of 192585567930, so I thought the answer has to be:

1. Either 192585567930
2. or this 1925855679300000000000

But both answers are wrong. Can someone help, please? Below is the part of the code with the solve a challenge function.

constructor(address fcn, address priceFeed) AFoundryCourseChallenge(fcn) {
    i_priceFeed = priceFeed;
}

function getPrice() external view returns (uint256) {
    (, int256 price,,,) = AggregatorV3Interface(i_priceFeed).latestRoundData();
    return uint256(price);
}

function getDecimals() private view returns (uint8) {
    return AggregatorV3Interface(i_priceFeed).decimals();
}

function getPriceFeed() external view returns (address) {
    return i_priceFeed;
}

function solveChallenge(uint256 priceGuess, string memory yourTwitterHandle) external {
    uint256 actualPrice = getPrice();
    if (getDecimals() == 8) {
        actualPrice = actualPrice * 10e10;
    }
    if (actualPrice + 3e18 > priceGuess && actualPrice - 3e18 < priceGuess) {
        _updateAndRewardSolver(yourTwitterHandle);
    } else {
        revert LessonFour__WrongPrice();
    }
}`

@lamtrinh259, from where you checked the price? Make sure to check the price from the correct pricefeeds contract. You can get the contract address by the function getPriceFeed() of LessonFour contract.

@shikhar229169 thank you so much! I solved it!

Apparently, I was missing 1 zero! I was reading too fast, and I thought it was just 1e10, but it was 10e10 --> That explained my missing zero!

So the correct answer was this - 1925855679300 ?

@tamoghna-dey I don't think it'd work if you just blindly copy my answer (you're welcome to give it a try) without understanding what the question is asking. Follow shikhar229169's advice above and you should get there.

I haven't blindly copied your answer, I am just asking if you got it as the answer or not. Price of ETH isn't the same now, anyways it ain't gonna work. And I have already solved it, thanks for your response.
