To determine how many ones blocks you need to add to change the model from 128 to 146, you can subtract 128 from 146.
146 – 128 = 18
Since the options provided are 10, 12, 14, and 16, it looks like there might be an error in the options, as none of them corresponds to 18.
If you’re able to check with your instructor or look into the question further, that would be great!
