Mixed review
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

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
