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
The translation moved point B(-5, -2) to B'(6, -5). Although a graph isn't necessary, it helps visualize what happened.
What happened to the x-coordinate of B? It changed from -5 to 6, an INCREASE of 11. So point B moved 11 units to the RIGHT.
What happened to the y-coordinate of B? It changed from -2 to -5, a DECREASE of 3. So point B moved 3 units DOWN.
What happened to the x-coordinate of B? It changed from -5 to 6, an INCREASE of 11. So point B moved 11 units to the RIGHT.
What happened to the y-coordinate of B? It changed from -2 to -5, a DECREASE of 3. So point B moved 3 units DOWN.
