Lets find the glasses first. To find the number of glasses she bought we need to multiple the amount per box by the amount of boxes. Lets x equal the total number of glasses.
x=30*16
Multiply the numbers
x=480
She bought 480 glasses
Now lets find the plates. We need to do the same thing. Multiple the number of plates per box by the number of boxes. Let y equal the number of plates
y=25*30
Multiply the two numbers
y=750
She bought 750 plates.
Now to find how many she ordered all together we need to add the two numbers we got. Let z equal the total
