Question

In a particular city, taxis charge an initial fee of $3.50 plus $1.60 per mile. how far can a passenger travel for $40.30?

Answer 1

1.60* x + 3.50 = 40.30

1.60 x = 40.30 - 3.50 = 40.30 - 3 - 0.5

1.60 x = 37.30 - 0.5

1.60 x = 36.80

160x = 3680

16x = 368

x = 23

$1.60*23 + 3.50 = (1 + 0.6)*23 + 3.50

= 23 + 13,8 + 3.50

= 36.80+3.50

= $40.30
