Hi!
To solve this, let's divide
625/250 = 2.5
So is the pattern.. x/2.5 = x2/2.5 = x3/2.5...
We can test this theory by multiplying
100 x 2.5 = 250
Since 250 comes before 100 in the sequence then our theory is correct!
So to find the next numbers, divide:
40/2.5 = 16
16/2.5 = 6.4
6.4 = 2.56
The answer is C.
Hope this helps! :)
58 stamps is the number she gets each week. So if she went for one week, 58*1=58. 58*2=116 and so on. Because we don't know the exact number of weeks, we say 58w or 58*w because you multiply however many number of weeks she collects.
You just have to add the numbers up.
So the perimeter is 47 ft.
