Question

The cost of a regular price ticket to a Saint Louis Cardinal baseball game was $60. During the World

Answer 1

1/5 of $60 is $12.

Therefore, 2/5 of $60 is $24.

If the price of tickets increased by 2/5 during the World Series, then during the World Series a ticket would've cost $60+$24=$84.

Answer 2

$60+\frac{2}{5}*60=60+24=84$

Just take into account that the current price, the price will increase by 0.4. So for the money you need to add 0.4 the old prices. After summing get the new price.
