Anaba is stacking cereal boxes in a pyramid-shaped display. the bottom layer has 10 boxes. there are two fewer boxes in each layer than the layer below. how many boxes are in display.

I think it is 30. I'm probably being stupid tho

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

96 39 cause 135 -96=39 im smart (i used a calculater)
