Hey Friend ✋✋✋
Let the cost of one box of paper clips be "x"
and index card be "y"
15x + 7y = 55.40.....× 2
12x + 10y = 61.70.... = 6x + 5y = 30.85.....×5
by eliminating
30x + 25y = 154.25
30x + 14y = 110.80 (-)
--------------------------
y = 43.45/11 = 3.95
y = 4(approx)
6x = 30.85 -19.75
x = 11.1/6 = 1.85 = 2(approx)
hope it helps
