for $95.94. The crate had 6 boxes of floor tiles. Each box
1. contained 20 floor tiles. Write and solve an

2. A convenience store sells two brands of orange juice. Brand A contains 8 fluid ounces and
costs $1.28. Brand B contains 12 fluid ounces and costs $1.68. What is the difference in cost, in
dollars, per fluid ounce between the two brands of juice?
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 : tiles
Now, cost of 6 boxes = $95.94
So, cost of 1 box (b) = = $15.99
20 tiles cost $15.99
Hence, 1 tile (t) will cost = = $0.799 ≈ $0.80
2.
Brand A contains 8 fluid ounces and costs $1.28.
Cost of per fluid ounce = = $0.16
Brand B contains 12 fluid ounces and costs $1.68.
Cost of per ounce = = $0.14
Difference between both the per ounce costs = = $0.02
