Final answer:
To find the final cost per night after the discount and tax, multiply the room rate by the percentage discount, subtract the discount amount from the original room rate, and then add the tax amount to the discounted rate.
Step-by-step explanation:
To find the final cost per night after the discount and tax, we need to first calculate the discount amount and then add the tax.The discount amount can be found by multiplying the room rate by the percentage discount: $58 * 0.15 = $8.70.Now subtract the discount amount from the original room rate to get the discounted rate: $58 - $8.70 = $49.30.
Finally, add the tax amount to the discounted rate: $49.30 + ($49.30 * 0.04) = $51.19.So, the final cost per night after the discount and tax is $51.19.
