Karen stayed at the Lunar Lodge last night. The room cost $174 plus a tax of 13%

Let x be the amount of tax for the room (in dollars). Using the values below, create a proportion that can be used to find x.
__________________________________________________________________________
Use the proportion from part (a) to find the amount of tax for the room. Do not round any computations.
______________________________________________________________________
What was the total cost of the room, including tax? Do not round any computations.

The proportion that can be used to find x is:

x/174 = 13/100

To find x, we can cross multiply:

100x = 174 * 13

100x = 2262

Divide both sides by 100:

x = 22.62

The amount of tax for the room is $22.62.

To find the total cost of the room, we add the cost of the room and the tax:

Total cost = $174 + $22.62 = $196.62

The total cost of the room, including tax, is $196.62.
