Answer:

80

Step-by-step explanation:

16     20

------------

x       100

i made 16/x because 16 is only a portion of the total, which i represent the total being x. 20/100 represents 20% as a fraction. you cross multiply and get:

20x = 1600

then solve for x.

20x/20 = 1600/20

x = 80

so the total was 80 cards.

this is a complex way i did it but there are easier options.
