T= total taxi cost
m= # of miles
Multiply the quantity (1 plus the tip) times ((mileage charge times the number of miles) plus the initial fee.)
T= (1 + 15% tip )($2.10m + $5 fee)
T= (1.15)[(2.10)(5.6) + 5]
T= (1.15)(11.76 + 5)
T= (1.15)(16.76)
T= $19.27
Total taxi ride is $19.27.
Hope this helps! :)
