Answer:
Let x be the nightly rate before tax.
We know that the total cost including tax is $200.02, which is 100% of the cost before tax plus 7% sales tax:
x + 0.07x = 200.02
Combining like terms on the left-hand side:
1.07x = 200.02
Dividing both sides by 1.07:
x = 186.91
Therefore, the nightly rate before tax is $186.91, rounded to the nearest cent.
