business is ordering copy paper. At one company, a box with 10 reams of paper costs $56. At another company, a box with 8 reams of paper costs $36. What is the unit price for each ream?

A. 0.18/ream/s1.00 and 0 22 ream/$1.00
B.0 5.60 reams/S1.00 and 4.50 reams/$1.00
C.• so.18/ream and $0.22/ream
D.• $5.60/ream and $4.50/ream

The unit price for each ream at the first company can be found by dividing the total cost of the box by the number of reams in the box: $56 / 10 = $5.60/ream.

The unit price for each ream at the second company can be found by dividing the total cost of the box by the number of reams in the box: $36 / 8 = $4.50/ream.

So, the correct answer is D. $5.60/ream and $4.50/ream.

To find the unit price for each ream of paper at each company, we need to divide the total cost of the box by the number of reams in the box.

For the first company:
Total cost of the box = $56
Number of reams in the box = 10
Unit price for each ream = Total cost of the box / Number of reams in the box = $56 / 10 = $5.60/ream

For the second company:
Total cost of the box = $36
Number of reams in the box = 8
Unit price for each ream = Total cost of the box / Number of reams in the box = $36 / 8 = $4.50/ream

Therefore, the correct unit prices for each ream are:
D. $5.60/ream and $4.50/ream

To find the unit price for each ream of paper, we need to divide the total cost of the box by the number of reams in the box.

Let's start with the first option:
A. 0.18/ream/$1.00 and 0.22/ream/$1.00

For the first company, a box with 10 reams of paper costs $56. To find the unit price for each ream, we divide $56 by 10:
$56 / 10 = $5.60/ream

For the second company, a box with 8 reams of paper costs $36. To find the unit price for each ream, we divide $36 by 8:
$36 / 8 = $4.50/ream

So, option A is incorrect as it suggests the unit prices are different.

Let's move on to the second option:
B. 0.5.60 reams/$1.00 and 4.50 reams/$1.00

Again, for the first company, the unit price is $5.60/ream, which matches the first option.

For the second company, the unit price is $4.50/ream, which also matches the first option.

So, option B is incorrect as it suggests the unit prices are different.

Now, let's check the third option:
C. $0.18/ream and $0.22/ream

Option C suggests the unit prices are the same, but this does not match the values we calculated earlier. So, option C is incorrect.

Finally, let's check the fourth option:
D. $5.60/ream and $4.50/ream

Option D matches the unit prices we calculated earlier, $5.60/ream for the first company and $4.50/ream for the second company. Therefore, the correct answer is option D.
