calvin is planning to go snow skiing . He went shopping for a jacket. The jacket was originally priced at $90 and was on sale 50% off. What is the price of the jacket now.

0.5 * 90 = $______

To find the price of the jacket after the 50% discount, we need to calculate half (50%) of the original price and subtract that amount from the original price.

First, we calculate half of $90:
50% of $90 = (50/100) * $90 = $45

Next, we subtract $45 from the original price of $90:
$90 - $45 = $45

So, after applying the 50% discount, the price of the jacket is now $45.
