A store owner wants to mix cashews and almonds. Cashews cost 2 dollars per pound and almonds cost 5 dollars per pound. He plans to sell 150 pounds of a mixture. How many pounds of each type of nuts should be mixed if the mixture will cost 3 dollars? Choose the correct choice from the following answers
A) 30
B) 40
C) 50
D) 60
E) 70
Let x be the number of pounds of cashews   So, 150 - x will represent the number of almonds   Since each pound of the mixture cost 3 dollars, 150 pounds will cost 3 × 150 = 450 dollars   Cost of cashews + cost of almonds = 450   2 × x + (150 - x) × 5 = 450   2x + 150 × 5 - x × 5 = 450   2x + 750 - 5x = 450   2x - 5x + 750 = 450   -3x + 750 = 450   -3x + 750 - 750 = 450 - 750   -3x = -300   -3x/-3 = -300/-3=
