Nadia receives a restaurant bill for £75.60 this bill includes an 8% service charge how much was the restaurant bill before the service charge

The restaurant bill before the service charge is: £69.55

Step-by-step explanation:

Service charge percentage = 8%

Total Bill including service charge = £75.60

Let us first determine the service amount using the formula

Service amount = 8% of 75.60

                          = 8/100 × 75.60

                          = £6.05

Thus, the restaurant bill before the service charge can be determined by subtracting the service amount from the total bill.

Restaurant bill before the service charge = Total Bill - Service amount

                                                                     = £75.60 - £6.05

                                                                      = £69.55

Therefore, the restaurant bill before the service charge is: £69.55
