Kaitlin stayed at the Green Lotus Inn last night. The room cost 58 plus a tax of 17%.
(a) 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.
Values:
_________ _________
(b) Use the proportion from part (a) to find the amount of tax for the room. Do not round any computations.
(c) What was the total cost of the room, including tax? Do not round any computations.
(a) 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.
The room cost: 58
Tax rate: 17%
x/58 = 17/100
(b) Use the proportion from part (a) to find the amount of tax for the room. Do not round any computations.
Cross-multiplying the proportion:
100x = 58 * 17
100x = 986
x = 986/100
x = 9.86
The amount of tax for the room is $9.86.
(c) What was the total cost of the room, including tax? Do not round any computations.
The total cost of the room is the room cost plus the tax:
Total cost = 58 + 9.86
Total cost = $67.86
