Answer: The first situation

Step-by-step explanation:

First, let's isolate the x in the equation:

$8x+5=29\\8x=29-5\\x=\frac{29-5}{8}$

$x=3$

If you want to calculate the cost of each shirt, that would be: the money that Angel has, minus the shipping charge, divided by the number of shirts that he bought.

If you want to calculate the number of shirts that Angel could buy, that would be: the money that Angel has, minus the shipping charge, divided by the cost of each shirt.

Then, for the second situation:

The money that Angel has is 29, the shipping charge is 5, and the number of shirts is 8. So the situation can be perfectly represented by the equation.

For the third situation:

The money that Angel has is 29, the shipping charge is 5, and the cost of each shirt is 8. So the situation can be perfectly represented by the equation.

The first situation is the only one that can't be represented by the given equation because:

The money that Angel has is 29, the shipping charge is 8 and the cost of each shirt is 5. If you substract the money that Angel has, minus the price of each shirt and then divide by the shipping charge you will not get the number of shirts that he can buy.
