Hailey took a taxi from her house to the airport. The taxi company charged a pick-up fee of $2.40 plus $4.50 per mile. The total fare was $87.90, not including the tip. Write and solve an equation which can be used to determine mm, the number of miles in the taxi ride.

The taxi drove Hailey for 19 miles.

Step-by-step explanation:

1. Subtract the tip.

$87.90 - $2.40 = $85.5

2. Divide by the price per mile. ($4.50)

$85.5 / $4.50 = 19

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

1/800 is the right answer
