But now they give you:
The total cost price of all the sales R510 000
The total selling price of all the goods R641 000
The total debtors allowance R29 000
And now you have to calculate the profit percentage...
Here is steps with formulas I worked out for this equation that will help:
Step 1: Selling Price - Cost Price - Debtors allowance = profit
Step 2: profit x 100
Cost price 1
= profit percentage
Example:
Step 1: R641 000 - R510 000 - R29 000 = R102 000
Step 2: R102 000 x 100
R510 000 1
= 20%
