here were 34 bales of hay in the barn. Dan stacked more bales in the bar
today. There are now 64 bales of hay in the barn. How many bales did he store in the barn?



Answer :

Well, you’re starting out with 34 bales of hay. So, that’s your starting point. Then you end up with 64 so that’s your ending point. The setup would be
34 + X = 64
Now to figure out x, you would subtract 34 on both sides to get
X = 64 - 34
Then, after the subtraction you’d get:
X = 30
Understand that this means Dan added 30 more bales of hay into the barn.
