A supermarket soup can display consists of 5 levels of
stacked cans. The figure below shows an overhead
view of the top level of cans (circles shaded and with
solid borders) and the level of cans below it (circles
with dashed borders). In the display, each level has
4 more cans than the level above it. How many cans
are in the display?

A supermarket shop cans display consists of 5 levels of  stacked cans. In the display, each level has  4 more cans than the level above it-the total number of cans in display are (b) 100

Step-by-step explanation:

Given that ,

The display consists of 5 levels of  stacked cans- which means that there are 5 levels in which the stacked cans are displayed .

so,the no:of levels are 5

Now given that level has  4 more cans than the level above it.

so. the number of cans in a single level = 5*4=20

Now we know that the total number of level is 5  so we multiply 20 withe the number of levels of can stacked

==>20*5=100

Thus we can say that the total number of cans in display are (b) 100

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
