Question
Burger King applies a fixed charge and an additional fee
for each burger ordered. 'Arun' and 'Vicky' placed orders for 180 and 120 burgers, respectively, resulting in Burger King charging them Rs. 17,000 and Rs. 14,000, respectively. Determine the amount that Burger King would charge when an order for 150 burgers is placed.Solution
ATQ, Let the fixed amount charged be Rs. 'p' and the extra amount charged for each Burger be Rs. 'q' According to the question, (p + 180q) = 17000…… (1) And, (p + 120q) = 14000….. (2) On solving equation (1) and (2), we get Fixed charge = p = Rs. 8000 And, charge per meal = q = Rs. 50 Therefore, amount charged for each burger = p + 150q = Rs.15500
