Answer:cost price of Mr. Buhari's key is #32,000.
Explanation:
To calculate the cost price (CP) of Mr. Buhari's key, we can use the profit percentage and the selling price (SP) given.
Let's assume the cost price is CP.
The profit percentage is 15%, which means the profit is 15% of the cost price:
Profit = 15% of CP = 0.15 * CP
The selling price is given as #36,800.
The selling price is equal to the sum of the cost price and the profit:
SP = CP + Profit
Substituting the value of the profit:
#36,800 = CP + 0.15 * CP
Combining like terms:
#36,800 = 1.15 * CP
To find the cost price, we need to divide both sides of the equation by 1.15:
CP = #36,800 / 1.15
Calculating the result:
CP ≈ #32,000
cost price of Mr. Buhari's key is #32,000.
