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.
