Question

The formula below is used by a company to work out the cost ,£A, of a taxi ride.

A=3+1.6m+c
£3 is a fixed charge
m is the number of miles travelling
£c is a charge for booking online
Harriet books a taxi online and travels 16 miles
she pays £30 altogether
how much is the charge for booking online?

Answer 1

A = 3 + 1.6m + c
30 = 3 + 1.6(16) +c
C = 30 - 1.6(16) + c
C = £1.4

Booking charge in online # 1.4 #

Answer 2

Harriet paid £30 for a taxi ride that covered 16 miles. The formula used by the company to calculate the cost of a taxi ride is given by:

A = 3 + 1.6m + c

where A is the cost of the ride, m is the number of miles travelled, and c is the charge for booking online.

We can substitute the values given in the problem statement to obtain:

30 = 3 + 1.6(16) + c

Simplifying this equation, we get:

c = 30 - 3 - 1.6(16) = £4.4

Therefore, the charge for booking online is **£4.4**.
