In order to get a thicker sauce, a restaurant owner combines a sauce that is 70% tomato paste with the original sauce, which is 40% tomato paste. How much of each should be used to make 5 L of the new 60% tomato paste sauce?
tomatoes in ingredients = tomatoes in final sauce
Amount of 70% = x
amount of 40% = (6-x)
70 % (x) + 40% (5 L - x) = 60% ( 5 L)
.7 x + .4 (5-x) = .6 (5) SOlve for 'x' the amount of 70% then 40% = 5-x
