Question

What is the better buy
1. 2 trains for $25
or
2.6 trains for 90$

Answer 1

2 trains for 25 because if you find the unit rate of both the first one has a lower rate

Answer 2

1.2 trains for $25.

Explanation:

For 50 dollars, you could get 2.4 trains with the $25 dollar option.

For 90 dollars (an extra 40 dollars!) you only get 0.2 more trains.

If you add another $25 to the current $50 on the other option, you get 3.6 trains.

So, 1.2 trains for $25 must be the better option as you can get an extra 1 train for 15 dollars less!

Hope this helps!

Also, who buys 0.2 or 0.6 of a train? -_-
