I hope I was helpful
Answer:
the selling price of the office equipment is R3040
Step-by-step explanation:
original price of the office equipment, C = R3800
discount for the selling price, d = 20% = 0.2
Discounted amount = 0.2 x R3800
= R760
The selling price of the office equipment is calculated as follows;
The selling price = original price - discounted amount
The selling price = R3800 - R760
= R3040
Therefore, the selling price of the office equipment is R3040
Answer:
18, 41
Step-by-step explanation:
simultaneous equation

x = 41
