How to get weighted sum depending on multipliers in column in Excel?

问题

I have the table in Excel:

In column C (Sum) I want to get sum this way:

• If in column A or B value is 1 then take Amount 48 and multiply by Multiplier (1) = 2.
• If in column A or B value is 0 then take Amount 48 and multiply by Multiplier (0) = 1,5.
• Then K1 and K2 summed.

---

So for row 2 the result in column C will be: 48*2 + 48*2 = 192.
For row 5 the result in column C will be: 48*1,5 + 48*2 = 168.

---

Is it possible to automate this process using Excel formula for C column (inspite of number of columns)?

回答1:

Or you could use Countif (no shorter though)

=COUNTIF(A2:D2,0)*I$2*I$1+COUNTIF(A2:D2,1)*I$3*I$1

回答2:

Use Ctrl+Alt+Enter when entering (since it's an array formula)

EDIT: I'm not great with formulas, so there is I'm sure a shorter alernative...
