Answer:
1. Cost of 80 sheets of paper = $ 4.8
2. Cost of 80 sheets of paper = $ 6.4
3. Cost of 880 sheets of paper = $ 93.8
Step-by-step explanation:
1) if 40 sheets of paper cost $2.40 how much would 80 sheets cost
Solution:
Price of 40 sheets of paper = $2.40
Price of 1 sheet of paper = 2.40/40
Price of 80 sheets of paper = (2.40/40)*80
= $ 4.8
2)if 25 sheets cost $2.00 how much would 80 sheets cost
Price of 25 sheets of paper = $2.00
Price of 1 sheet of paper = 2.00/25
Price of 80 sheets of paper = (2.00/25)*80
= $ 6.4
3)if 15 sheets cost $1.60 how much would 880 sheets cost
Price of 15 sheets of paper = $1.60
Price of 1 sheet of paper = 1.60/15
Price of 880 sheets of paper = (1.60/15)*880
= $ 93.8
