put this solution on YOUR website!a grocer mixes 12kg of one grade of beans with 10kg of another grade to obtain a blend worth 540 pesos. he then makes a second blend worth 610 pesos by mixing 8kg of the first grade with 15kg of the second grade. find the price per kilogram of each grade?
---------------------------------------
Let "a" be the price of 1st bean and "b" be the price of 2nd bean.
--------------------------------------
Value Equation: 12a + 10b = 540
Value Equation: 8a + 15b = 610
-------------------
Solve the system by substitution, elimination, or matrix to get:
a = 20 p
b = 30 p
