A taxi charges $2.00 for up o and including the first mile,and $1.60 for each mile thereafter. What would the tax charge for a trip of 4 miles

For a trip of 4 miles, the taxi would charge for the initial mile plus an additional 3 miles. The charge for the initial mile is $2.00, and the charge for each additional mile is $1.60. So the total charge would be:

$2.00 (for the first mile) + $1.60 x 3 (for the additional 3 miles) = $2.00 + $4.80 = $6.80

Therefore, the taxi would charge $6.80 for a 4-mile trip.
