jorge bought a crate of floor ties
for $95.94. the crate had 6 boxes of floor tiles. each box
1. contained 20 floor tiles. write and solve an
equation to determine the cost per box, b. then
write and solve a second equation to determine the cost per tile, t, to the nearest cent.
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

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
