there were 8 rows of picture frames at the store. there are 7 picture frames in each row. twelve picture frames are sold. how many picture frames are left at the store?

Respuesta :

Answer:

44 are left

Step-by-step explanation:


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
