Hey!

The constant of proportionality is 0.27!
We could write a word problem for this. Like:
Jared had paid $0.27 for one pencil. How much would it cost to buy 5 pencils?
0.27 x 1 = $0.27
0.27 x 2 = $0.54
0.27 x 3 = $0.81
0.27 x 4 = $1.08
0.27 x 5 = $1.35
We can see that if Jared bought 5 pencils for $1.35. Since the proportionality is 0.27 just multiply how many times you need to.
We could also write this as:
