The total amount will be $950.5125
Given data
Length of room = 15ft
Width of room = 14ft
Let us find the area of the room
Area = Length*Width
Area = 15*14
Area = 210 square feet
Hence she will spend = 210*4.25
=$892.5
She will need to purchase tile worth $892.5
Let us factor in the tax
6.5%
Total cost = 6.5/100*892.5 + 892.5
Total cost =0.065*892.5 + 892.5
Total cost =58.0125 + 892.5
