Anna took a taxi from her house to the airport. The taxi company charged a pick-up fee of $3 plus $2.25 per mile. The total fare was $48, not including the tip. How many miles was the taxi ride?

Answer 1

Let x= miles traveled and y= cost. This is a linear function with a constant charge (y - intercept) of $3 and a variable charge of $2,25 per mile(slope) traveled. The equation used would be as follows:

y = $2.25x + $3. So, plug $48 into the equation for y and solve for x.

$48 = $2.25x + $3

So x= 20 miles

Answer 2

20 miles

20 x 2.25 = 45

45+3 = $48
