Question

8.

A one-way bus trip costs $1.25. A monthly
bus pass costs $41. Write and solve an
inequality to find the least number of one-
way rides you must take for the bus pass to
be a better deal than paying by the ride.

Answer 1

Lets say you must take x one-way rides. And you want the cost of the one-way rides’ total to be bigger than the pass so that it’s a better deal:

1.25x > 41

Now solve:

1.25x > 41
x > 41/1.25
x > 32.8

There are no rides sold in decimals so you have to round it up to 33. The least number of one-way rides is 33.
