Answer provided by our tutors
let
x = the number tables
y = the number of chairs
the number of chairs needed for a table arrangement is two more than four times the number of tables:
y = 2 + 4x
when the number of tables is 16 that is x = 16 for y we find:
y = 2 + 4*16
y = 66 chairs
66 chairs are needed when 16 tables are used.
