We are doing rate Ribbon costs $1.44 for 3m a). What is the cost per meter? b). How much would 5 m of ribbon cost? c). How much ribbon could you buy for $12.00 |
The clue here is the units. For example in part a) you want the cost
per metre. That will be in the units of dollars per metre or dollars
over metres. So take the number of dollars and divide by the number
of metres.
