Emma is installing a new tile floor. Each tile measures 12 inches by 12 inches. The room in which she is installing the tiles measures 14 feet by 10 feet. If each tile costs $1.25, how much will it cost Emma to complete her project?

first, we convert the given in same units,, let's use ft as units,, since 12 inches = 1 foot, we convert the given dimensions for the tiles into ft:

12 inches = 1 ft

12 inches = 1 ft

then we get the areas of both tiles and floor area to be installed by tiles:

A,tile = 1*1 = 1 sq ft

A,floor = 14*10 = 140 sq ft

dividing 140 and 1

140/1 = 140 tiles

each tile costs $1.25 so, we multiply this to the umber of tiles:

1.25*140 = ?

now solve for the product~

hope this helps~ :)
