Answer: The total cost of one box of paper = $ 1.85,
The total cost of one package of index cards = $ 3.95
Step-by-step explanation:
Let x represents the total cost of one box of paper any y be the total cost of one package of index cards.
Thus, According to the question,
15 x + 7 y = 55.40 ------(1)
12 x + 10 y = 61.70 -------(2)
4 × equation (1) and 5 × equation (2)
We get,
60 x + 28 y = 221.6 --------(3)
60 x + 50 y = 308.5 --------(4)
Equation (4) - equation (3),
We get, y = 3.95
By putting this value in equation (1),
We get, x = 1.85
Therefore, The total cost of one box of paper is $ 1.85 and The total cost of one package of index cards is $ 3.95.
