If you pay for $25.00 for purchase which includes 11% sales tax. how much is the sales tax?
Delvig [45]
Since it includes 11% sales tax, this means that (purchase)+11% of (purchase)=25.00. Since 11% = 0.11 by multiplying it by 1/100, we have 1*purchase+0.11*purchase=1.11*purchase=25.00. Dividing both sides by 1.11, we get around 22.73 as the original purchase. This means that the difference between the purchase price and the total price is the sales tax, which is around 2.27 dollars.

The area of the closet floor is 18 feet. If Saroya buys 32 tiles will she have enough to cover the floor?
kvasek [131]
No shel will not have enough tile.  If you don't know the dimensions of the actual tile how will you solve.  If you have a closet 18 square feet it could be 9 ' x 2 ' = 18 square feet. If the tiles were 12" x 6" you would need 36 tiles.  If the closet was 6' x 3' = 18 square feet you could have the tiles 12" x 6" = 36 tiles.  So you need to know the dimensions of the tile.
