James researched these nutrition facts:
1 gram of soy milk has 0.005 g of carbohydrates and 0.030 g of protien
1 gram of vegetables has 0.14 g of carbohydrates and 0.030 g of protien
James wants his lunch to have 50.000 g of carbohydrates and 20.000 g of protien. How many grams of soy milk and vegetables does he need?
answer is: 320.988g of soy milk and 345.679 g of vegetables
please teach me how to solve it!!!
Re: math help needed!
Here you go...
Amount of soy James needs= x grams
Amount of veggies James needs= y grams
(x)(0.005) + (y)(0.14) = 50 ________ I
(y)(0.03) + (x)(0.03) = 20 ________ II
multiply I by the LCM 6 and subtract from II
you get y = 345.679 grams
x = 320.988 grams
