Answers with working:

1.

Cost of a crate of floor tiles = $95.94

The crate has 6 boxes of floor tiles. This means 6 boxes of tiles cost $95.94

Now each box has 20 floor tiles.

So, total tiles in a box are : $t=6\times20=120$ tiles

Now, cost of 6 boxes = $95.94

So, cost of 1 box (b) = $b=\frac{95.94}{6}$ = $15.99

20 tiles cost $15.99

Hence, 1 tile (t) will cost = $\frac{15.99}{20}$ = $0.799 ≈ $0.80

2.

Brand A contains 8 fluid ounces and  costs $1.28.

Cost of per fluid ounce = $\frac{1.28}{8}$ = $0.16

Brand B contains 12 fluid ounces and costs $1.68.

Cost of per ounce = $\frac{1.68}{12}$ = $0.14

Difference between both the per ounce costs = $0.16-0.14$ = $0.02
