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

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
