1. your favorite book is $29.50, how much is it with tax?
2. A new bed set is $45.00, it is 15% off discount with the tax
3. Your brother's baseball costs $53.35 a month, but now they added 23% of the original cost to it, how much is it now?
Note: each answer needs tax of 7.725%
I'll show you how to do one of these. Which one do you want me to do for you?
the third one please
53.35 * 1.23 = 65.62
65.62 * 1.07725 = 70.69
To calculate the final price including tax, you can follow these steps:
1. Determine the tax amount by multiplying the pre-tax price by the tax rate. In this case, the tax rate is 7.725%.
1.1 For the first question:
Pre-tax price = $29.50
Tax rate = 7.725%
Tax amount = $29.50 * 0.07725 = $2.28 (rounded to 2 decimal places)
2. Add the tax amount to the pre-tax price to get the final price.
2.1 For the first question:
Pre-tax price = $29.50
Tax amount = $2.28 (calculated in the previous step)
Final price = $29.50 + $2.28 = $31.78
Now let's calculate the final prices for the other two questions.
2. For the second question:
Pre-tax price = $45.00
Tax rate = 7.725%
Tax amount = $45.00 * 0.07725 = $3.47 (rounded to 2 decimal places)
Final price = $45.00 + $3.47 = $48.47
3. For the third question:
Original cost = $53.35
Additional percentage = 23%
Tax rate = 7.725%
The additional cost can be calculated by multiplying the original cost by the additional percentage:
Additional cost = $53.35 * 0.23 = $12.27 (rounded to 2 decimal places)
Tax on the original cost = $53.35 * 0.07725 = $4.12 (rounded to 2 decimal places)
Tax on the additional cost = $12.27 * 0.07725 = $0.95 (rounded to 2 decimal places)
Final price = Original cost + Additional cost + Tax on the original cost + Tax on the additional cost
= $53.35 + $12.27 + $4.12 + $0.95 = $70.69
So, the final prices for the given scenarios are:
1. $31.78
2. $48.47
3. $70.69
