I have the following formula in one of my cells:

=IF(C5<0,C6 &" Supplied by Marketing - Calculated value is " &C4,C4&"
Calculated value")

The values in C4, C5, C6 are all in dollar format but the output doesn't
show in dollar format. See below:

7500 Supplied by Marketing - Calculated value is 8800 .

Any way to get the format like this:

$7,500.00 Supplied by Marketing - Calculated value is $8,800.00
