It is typical one-unknown problem. Let x be the number of quarters. Then the number of dimes is 2x, according to the condition. Then the number of nickels must be (95-(x+2x)) = (95-3x). The money equation is 5*(95-3x) + 10*(2x) + 25*x = 1075 cents. Simplify and solve for x: 5*95 - 15x + 20x + 25x = 1075 30x = 1075 - 5*95 30x = 600 ====> x == 20. Answer. 20 quarters, 2*20 = 40 dimes and (95 - 20 - 40) = 35 nickels.
