price of milk example

1.	Figure out the multiplier for the first step:
(a)	Tuesday’s price is __36_ % more than Monday’s price.
(b)	Tuesday’s price is _136_ % of Monday’s price.
(c)	Tuesday’s price is _1.36_ times Monday’s price.

2.	Figure out the multiplier for the second step:
(a)	Wednesday’s price is _15_ % less than Tuesday’s price.
(b)	Wednesday’s price is _85_ % of Tuesday’s price.
(c)	Wednesday’s price is _0.85_ times Tuesday’s price.

3.	Calculate the over-all multiplier:
(a)	Tuesday’s   price is _1.36_ times Monday’s price.
(b)	Wednesday’s price is _0.85_ times Tuesday’s price.
(c)	Wednesday’s price is _1.156_ times Monday’s price.

4.	Interpret the results:
(a)	Wednesday’s price is _115.6_ % of Monday’s price.
(b)	Wednesday’s price is __15.6_ % MORE THAN Monday’s price.


price of cocoa example

(a)	Tuesday’s price is _270_ % more than Monday’s price.
(b)	Tuesday’s price is _370_ % of Monday’s price.
(c)	Tuesday’s price is _3.70_ times Monday’s price.

2.	Figure out the multiplier for the second step:
(a)	Wednesday’s price is _80_ % less than Tuesday’s price.
(b)	Wednesday’s price is _20_ % of Tuesday’s price.
(c)	Wednesday’s price is _0.20_ times Tuesday’s price.

3.	Calculate the over-all multiplier:
