Answer

Uber

Work Step by Step

We find the initial cost for each company. For Uber: $$ =1.25+(2.89)(5) = 15.7$$ For the taxi: $$ =4.75+(2.55)(5) =17.5$$ For Lyft: $$ = 2.6+ (2.76)(5) =16.4$$ We divide the cost by 5 miles to get the cost per mile. For Uber: $$=15.7\div 5 = 3.14$$ For the taxi: $$ = 17.5\div 5 =3.5$$ For the Lyft: $$ =16.4\div 5 = 3.28$$ The best deal is the Uber.
