pyramid of cards.
a) Create a table of values to show the relationship between the number levels (l) (starting with the top
one) and the number of cards (c) for that level.
b) Graph the relationship.
c) Write an equation to show the relationship.
d) Which is the independent variable and which is the dependent variable?
e) How many cards will be required for a 12th level? Use your equation from part (c) and show your
work.
