Ahomeowner plans to remodel her bathroom,- and she’s chosen 1-foot-by-1 foot ceramic tiles for the floor. the bathroom is 8 feet 6 inches long and 7 feet 4 inches wide. (a) how many tiles does she need to cover the floor of her bathroom? (b) each tile cost $4.how much will it coat to tile her floor? (c) the store from which she purchases the tile offers a discount of 10% on orders over $250. does her order qualify for the discount ?

a.)102*88=8976 in total.

8976/12=748 tiles

b.) 4*748=2992 dollars

c.) yes it qualifies

hope this is correct, if not, sorry for the inconvenience...

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

a: 1/6, j: 1/4
