If there are 10 items per small box and 4 boxes were delivered, we can find the total number of items in the small boxes by multiplying 10 and 4. 10*4 = 40
Likewise, we can do the same thing with the large boxes by mutliply 25 and 6. 25 * 6 = 150
Finally, we can add these two together to find the total number of items she recieved is 190 items.
