Altering a cell value wih multiple 'If' conditions which require a seperate multiplier

[JNM71]

Hi everyone

I am new to this forum and excel, so forgive me if this is a stupid / particularly simple question!

I am building a labour and wages tracking spreadsheet. It is nearly complete but I need assistance adding 1 formula which would calculate:

CELL NR7=Cell K7

However

If CELL K5= Saturday, then CELL NR7=CELLK7 * 1.5
and
If CELL K5= Sunday, then CELL NR7=CELLK7 * 2
and
If CELL K5= Bank Holiday, then CELL NR7=CELLK7 * 1.5
and
CELL K5= Christmas Day, then CELL NR7=CELLK7 * 2
and
If CELL K5= Good Friday, then CELL NR7=CELLK7 * 2

Hope someone can help!
