Many people in the U. S. think that the penny should be eliminated from economy, but 67% of people think that it still should be minted. If a sample of 15 people were randomly selected, how many of the 15 are expected to say that they want the U. S. to continue making the penny?

Step-by-step explanation:

It's true that it costs more to mint these two coins than they are worth. In 2017, it cost the U.S. Mint 1.8 cents to make each penny and 6.6 cents for each nickel. ... For every dollar's worth of coins it shipped out, the Mint made 45 cents.

combine all like terms then its just a 2 step equation

you can use a^2+ b^2=c^2
