Intro Number Entries

This intro problem practices COUNT. COUNT tells you how many cells in a range contain numbers. Text and blank cells are ignored. Update the output cells so each row shows how many entries in columns C through F are numbers. See Examples

Your solution should use cell references so it updates automatically if the input cells change values.
