Answer:
120
Step-by-step explanation:
20*12=240
240/2=120
Find the area of the room by multiplying the length by the width:
Area of room = 20 x 12 = 240 square feet.
Find the area of the tile: 2x 2 = 4 square feet.
To find the number of tiles divide the area of the room by the area of a tile:
240/4 = 60
They will need 60 tiles.
10,200 Dollars
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 7500(1 + (0.06 × 6)) = 10200
A = $10,200.00
