  1. To find the answer, you should divide 405 by 50 to find the mass of one coin. The formula should look like this:
    [tex]\frac{405}{50}[/tex]
    = 8.1
    The exact mass is 8.1 grams, but because you want an estimate, the answer should be
    About 8 grams for the mass of 1 one-dollar coin

  2. Hello!

    At the bank, Brent exchanges $50 in bills for 50 one-dollar coins. The total mass of the coins is 405 grams. ESTIMATE the mass of 1 one-dollar coin

    Data:  

    $50 dollars in bills → 50 coins of one dollar  

    Estimate the mass of one dollar coin

    Solving:  

    50 coins → 405 grams

    1 coin → y

    [tex]\dfrac{50}{1} = \dfrac{405}{y}[/tex]

    The rule of three

    [tex]50*y = 405*1[/tex]

    [tex]50\:y = 405[/tex]

    [tex]y = \dfrac{405}{50}[/tex]

    [tex]\boxed{\boxed{y = 8.1}}\end{array}}[/tex]

    [tex]\boxed{\boxed{\boxed{x \approx 8\:grams/coin}}}\qquad\checkmark[/tex]

  3. If he has 50 evenly weighted coins and combined their total weight is 405g. Then to find the weight per coin we must divide the total weight by the amount of coins.

  4. $50 dollars in one-dollar coins = 405 grams

    simply divide 405 grams by 50 coins which equals 8.1 grams

    The answer to your question would be ~8 grams per coin
