The price of one pound of sugar is 7 pesos
Step-by-step explanation:
The question in English is
6 pounds of coffee and 5 pounds of sugar cost 227 pesos and 5 pounds of coffee and 4 pounds of sugar (at the same prices) cost 188 pesos Find the price of one pound of coffee and one pound of sugar.
Let
x-----> the price of one pound of coffee
y-----> the price of one pound of sugar
we know that
6x+5y=227 -----> equation A
5x+4y=188 ----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (32,7)
see the attached figure
therefore
The price of one pound of coffee is 32 pesos
The price of one pound of sugar is 7 pesos
