Marty booked a hotel room that cost $225.00. Sales tax on the room was 12%. What was the total cost of the hotel including tax?

First, find the tax

tax = 12% * cost

tax = 12/100 * 225

tax = 0.12 * 225

tax = 27

The tax was $27

Second, add the cost and tax together to find the total cost

total cost = cost + tax

total cost = 225 + 27

total cost = 252

The total cost was $252.00
