it is easy to type this in Java

Explanation:

class pennies 1

{

public static void main ()

{

System.Out.println("Here’s an old problem. Today, I’ll give you a penny. Tomorrow, I’ll give you two pennies. I’ll keep doubling the amount I’ll give you for 30 days. How much will you have at the end of the month (better use a long integer type to keep track)?")

}

}

hey there! :

mass = 5.75 g

volume = 7.5 cm³

therefore:

density = mass / volume

d = 5.75 / 7.5

d = 0.7 g/cm³

answer c

hope that !
