Calculate hotel saving

The cost of staying one night at a hotel in Amber City is forty-five dollars. The cost of staying one night at a hotel in Bear Lake is one-hundred forty-five dollars. Find the amount saved on a 4 night stay in Amber City instead of Bear Lake.

Solution # 1

4 nights in Amber cost 45 * 4 = 180

4 nights in Bear Lake cost 145 * 4 = 580

The saving is 580 - 180 = 400

Solution # 2

Saving for one night in Amber is 145 - 45 = 100

So, saving for 4 nights is 100 * 4 = 400
