if the border for the first bedroom costs $1.95 per foot,the second bedroom is $1.45 per foot, the third bedroom is $1.75 per foot, and the sales tax rate is 5.5%, what will the total cost be?
You require additional data on the linear size of each bedroom's "border"
$283.90
To find the total cost, we will need to calculate the cost of each bedroom separately and then add them together, including the sales tax.
Let's calculate the cost of each bedroom:
Cost of the first bedroom:
Border cost per foot: $1.95
Let's say the first bedroom has a border length of 'x' feet.
So, the cost of the border for the first bedroom can be calculated as: 1.95 * x = $1.95x
Cost of the second bedroom:
Border cost per foot: $1.45
Let's say the second bedroom has a border length of 'y' feet.
So, the cost of the border for the second bedroom can be calculated as: 1.45 * y = $1.45y
Cost of the third bedroom:
Border cost per foot: $1.75
Let's say the third bedroom has a border length of 'z' feet.
So, the cost of the border for the third bedroom can be calculated as: 1.75 * z = $1.75z
Now let's calculate the total cost by adding up the costs of all three bedrooms:
Total cost = ($1.95x) + ($1.45y) + ($1.75z)
Lastly, we need to consider the sales tax rate of 5.5%. To calculate the sales tax, we need to multiply the total cost with the tax rate:
Sales tax = Total cost * 5.5% = Total cost * 0.055
Final total cost = Total cost + Sales tax
Now you can substitute the values of 'x', 'y', and 'z' with the lengths of each bedroom's border, and calculate the final total cost.
