The price of a ream of paper is $3.30. There are 500 sheets of paper in a ream. If a sheet of paper weighs 0.500 oz, what is the price of a kg of paper (in dollars, do not include units, round to two decimal places)?
What is the cost of one sheet of paper (in dollars, do not include units, round to four decimal places)?
What is the mass (grams) of one sheet of paper ( do not include units, round to one decimal place)?
Not sure I understand why you are instructed to not include units as this goes against good science teaching practice.
But anyway
if $3.30 /ream
then £3.30/500 sheets
which is $0.0066 sheet^-1 tp four dp.
1.000 oz is 0.02835 kg
0.500 oz is 0.01413 kg or 14.13 g
thus 1 kg of paper is
1 kg/0.01413 kg sheet^-1
=70 sheets to the nearest whole sheet
so 1 kg of paper costs
70 sheets x $0.0066 sheet^-1
=$0.46
Please check the maths and remove the units if you want to.
To find the price of a kg of paper, we first need to find the price per gram of paper.
The weight of one sheet of paper is 0.500 oz, which is approximately 14.1748 grams.
The price of a ream of paper is $3.30, and there are 500 sheets in a ream.
Therefore, the price of one sheet of paper is $3.30 / 500 = $0.0066 (rounded to four decimal places).
To find the price per gram, we divide $0.0066 by 14.1748 grams:
Price per gram = $0.0066 / 14.1748 grams ≈ $0.00046 (rounded to five decimal places).
Next, to find the price per kg, we multiply the price per gram by 1000 (since there are 1000 grams in a kg):
Price per kg = Price per gram × 1000 = $0.00046 × 1000 = $0.46 (rounded to two decimal places).
Therefore, the price of a kg of paper is $0.46.
To find the mass of one sheet of paper in grams, we already know that it is approximately 14.1748 grams (rounded to one decimal place).
To find the price of a kg of paper, we need to first find the price of one sheet of paper and then convert it to the price per kg.
To find the price of one sheet of paper:
1. Divide the price of a ream of paper by the number of sheets in a ream:
$3.30 / 500 = $0.0066
So, the cost of one sheet of paper is $0.0066.
To find the price of a kg of paper:
1. Convert the weight of one sheet of paper from ounces to kilograms:
0.500 oz = 0.500 * 0.02835 kg = 0.014175 kg (rounded to six decimal places)
2. Divide the cost of one sheet of paper by its weight in kg to get the price per kg:
$0.0066 / 0.014175 kg = $0.4645
So, the price of a kg of paper is $0.46 (rounded to two decimal places).
Now, to find the mass of one sheet of paper:
1. Convert the weight of one sheet of paper from ounces to grams:
0.500 oz = 0.500 * 28.3495 g = 14.175 g (rounded to one decimal place)
So, the mass of one sheet of paper is 14.2 grams.
