math problem word question, can u write it on the picture it's easier to understand that way when it's separate

As a first step we can notice that in three hours at a rate of 52 boxes an hour, they produce:
[tex]3\cdot52=156\text{ boxes}[/tex]If they have 404 boxes in stock, they must have had:
[tex]404-156=248\text{ boxes}[/tex]when the store opened.
Then, the expression that represents the situtation would be:
Let b the number of boxes.
Let h number of hours since they opened.
[tex]\begin{gathered} b=52h+248 \\ \text{where, } \\ 52\text{ is the rate of change } \\ \text{and 248 is the initial value} \end{gathered}[/tex]Now, to calculate how many boxes they will have at the end of an 8 hour shift, we just have to susbtitute h=8.
[tex]\begin{gathered} b=52\cdot8+248 \\ b=664 \end{gathered}[/tex]At the end of the shift, they will have 664 boxes.
