I did not understand your steps. You mentioned “Step 3) Sum the below for other costs. Note: these are unchanged so take the amounts as listed. Amortisation + Accounting admin costs”
This should be as follows: (10% * 80) + (20%*160)
Furthermore the final calculation:
Step 4) Total everything to get your final answer: S1) TOTAL SALARY COST X S2) TOTAL SALARY COST * 25% X S) TOTAL OTHER COSTS X TOTAL = ANSWER
do we need to multiply Step 1 * Step 2 * Step 3? Please. Thank you
