Given that:
Initial number of bales of hay = 1041 bales
After stacking more bales in the barn:
Total number of bales after stacking = 2,358 bales
Equation for scenario b
Initial bales + added bales = total number of bales after stacking
Let added bales = b
1,041 + b = 2,357
Added bales = Newly stacked bales:
1041 + b = 2,357
b = 2357 - 1041
b = 1,316
The stacked bales of hay stacked to join the initial is. 1,316 bales
