Michael could add up four lots of $2.85 and get $11.40. This would not be difficult. But, what if he wanted to buy 44 bottles!

2.85 

2.85

2.85

2.85 +

1.44

Michael could count.

four lot of $2    = 8.00

Four lots of 80 cents     = 3.20

Four lots of 5 cents    = 0.20

$2.85 X 4

=$3 X 4 - 15 cents X 4

=$12-60 cents

=$11.40

Michael work out

    2.85

    $11.40
