Answer:
The boys club sold 52 bags of hardwood mulch and 84 bags of pine bark mulch
Step-by-step explanation:
Let
x ----> the number of bags of hardwood mulch sold
y ----> the number of bags of pine bark mulch sold
we know that
A local boys club sold 136 bags of mulch and made a total of $400
so
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
Using a graphing tool
The solution is the point (52,84)
see the attached figure
therefore
The boys club sold 52 bags of hardwood mulch and 84 bags of pine bark mulch
Answer:
No solution
Step-by-step explanation:
So we have the equation:
First, subtract 20 from both sides:
Now, we can stop. Recall that absolute value will always <em>always</em> give a positive answer.
Since this equals -16, this means that there is no solution.
And we're done!
