A ride in a cab costs $0.40 plus $0.15 per mile.

a.Write an equation for traveling x miles in the cab.

0.4 + 0.15x = t

ride=.40+.15x

The equation for traveling x miles in the cab would be:

Cost = $0.40 + $0.15x

To write an equation for traveling x miles in the cab, we need to consider the cost of the initial ride plus the cost per mile.

The initial cost is $0.40, and for each mile traveled, there is an additional cost of $0.15. Therefore, the equation can be written as:

Cost = 0.40 + 0.15x

In this equation, x represents the number of miles traveled, and the equation calculates the total cost of the ride.
