Question

The total cost after tax to buy floor tiles is represented by 14f + 0.097(14f), where f represents the number of square feet of tile are need to cover the floor.. a. What part of the expression represents the amount of tax that must be paid? Explain.​

Answer 1

Answer:

exActual room size: 8 ft 7 in x 5 ft 2 in

Convert to inches, actual room size: 103 in x 62 in

103" x 62"= 6386 inches / 144 (1 sf) = 44.50 sf + waste factor (44.50 x 1.10) = 49 sf

The same method is used when measuring walls. Measure the area to be tiled on each wall. Add them together and figure the square footage. Add your waste factor and this is the amount needed.

Most vertical applications will require trim pieces which have finished edges, this requires a linear measurement. Trim pieces will be used:

1. Where a tiled surface ends on an open wall leaving an exposed tile edge,

2. Where a vertical surface meets a horizontal, like on the edge of a countertop,

3. Where a vertical surface turns a corner, like on the outside corner of a wall.

Trim pieces and decoratives are typically sold by the piece. To figure the quantity you have to establish the length of the trim piece (i.e. 6" bullnose, 8" decorative liner), then the rule is: Linear Inches/Piece Length = Quantity
