On the first swing, a pendulum swings through an arc of length 65 cm. on the successive swing, the length of the arc is 85% of the length of the previous swing. write a rule to model this situation.

you mutliply 65 to 85%/0.85 and you get 55.25cm as your answer

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
