Ответ:
Should be used 28 pounds of pecans and 32 pounds of chocolate candies
Let
x > pounds of pecans used
y > pounds of chocolate candies used
we know that
> equation A
> > equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
Using a graphing tool
The solution is the point (28,32)
see the attached figure
therefore
Should be used 28 pounds of pecans and 32 pounds of chocolate candies
