what is the fewest number of round tables that kathleen needs so that each guest will have a seat?

choose all answers that are correct.

a.

draw a diagram.
eight people at 1 table, 4 people at round table, 4 people at round table, 4 people at round table, 4 people at round table, 4 people at round table. count the number of round tables.

b.

use logical reasoning.
start with 28 people, subtract 8 people who will sit at the dining room table, that leaves 20 people. keep subtracting 4 people until you get to 0. count how many times you subtracted 4 people.

c.

translate into an equation.
28 – 8 + 4 + 4 = t

d.

work backward.
there are 28 people coming to the party. there is one dining table, so subtract 1. now figure out how many round tables there are and subtract that number.
