How many 2.5 inch by 6 inch tiles will fit on a backsplash that is 2.5 feet tall and 8 feet long? If each tile cost 80 cents how much change would you get back

Question

if each tile costs 80¢ how much change will you get back if you paid in 100$ bills

Answer 1

(2.5 ft)(12 in/ft) = 30 inches

(8 ft)(12 in/ft) = 96 inches

 

(30 in)(1/ 2.5 tiles/in) = 12 tiles tall

(96 in)(1/6 tiles/in) = 16 tiles long

 

12(16) = 192 tiles

(192 tiles)(0.8 $/tile) = $153.60 cost

 

$200 - $153.60 = $46.40 change

Answer 2

16 tiles along the length by 12 high.

How many is that?

 

Now multiply by the cost of each.
