Question

Two books have a total of 345 pictures of dogs. The first book has 121 pictures of dogs. How many pictures of dogs are in the second book? A 466 pictures B 225 pictures C 214 pictures 224 pictures

Answer 1

For this case the total of pictures are 345

We know that pictures from the first book are 121

Then we can create the following equation:

345= 121 +x

Where x= number of pictures for the second book

And solving we got:

x= 345-121= 224

Then the answer would be:

224 pictures
