For this case we have The following data:
- 8 rows of picture frames
- 7 photo frames per row
To know the amount of total frames in the store, we make a rule of three:
7frames ------> 1row
x ----------------> 8rows
Where x represents the number of frames in 8 rows, so, we have:
[tex]x=\frac{(8*7)}{1}[/tex]
[tex]x=\frac{56}{1}[/tex]
[tex]x=56[/tex]
Thus, there is a total of 56 frames in the store.
Now, if 12 picture frames are sold, then:
[tex]y = 56-12[/tex]
Where and represents the number of frames of photo frames left in the store, after selling 12, subtracting is:
[tex]y = 44[/tex]
So, there are 44 frames left in the store.
Answer:
44 frames
