At the store, 6 pencils sell for $.99. At this rate what is the cost of 16 pencils?
How do YOU think you should solve this?
i don't know its confuses me
Set up a proportion like I showed you a few minutes ago.

9.9/6 = x/16
or how would i writea proportion for that?
Almost right.
0.99/6 = x/16
To find the cost of 16 pencils, we can use the given price for 6 pencils and calculate the unit price per pencil. Then, we can multiply this unit price by 16 to find the total cost.
Step 1: Calculate the unit price of one pencil
Divide the total cost of 6 pencils ($.99) by the number of pencils (6):
$.99 / 6 = $0.165
Step 2: Multiply the unit price by 16
Multiply the unit price ($0.165) by the number of pencils desired (16):
$0.165 * 16 = $2.64
Therefore, the cost of 16 pencils is $2.64.
