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.

  1. 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?

Verified Answer :

  1. b = $95.94 / 6
           = $    15.99

        t = $15.99 / 20
          = $    0.80

    2. A: $1.28 / 8 = $0.16 per oz
        B: $1.68 / 12 = $0.14 per oz 

        Difference: $0.02 per oz

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) = @@MATH_TOKEN_1@@ = $15.99

20 tiles cost $15.99

Hence, 1 tile (t) will cost = @@MATH_TOKEN_2@@ = $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 = @@MATH_TOKEN_5@@ = $0.02
