Express each ratio as a unit rate. round to the bearest tenth, if necessary. 2 note books for $0.60

(a) $1.20 per notebook
(b) $0.30 per notebook
(c) $3.33 per notebook
(d) $0.60 per notebook

Option B

2 notebooks for $ 0.60 expressed as unit rate is $ 0.30 per notebook

We have to express ratio as unit rate

Given that, 2 notebooks for $ 0.60

Number of notebooks = 2

Cost of 2 notebooks = $ 0.60

So we have to find cost of 1 notebook

So unit rate = cost of 1 notebook = $ 0.30

So 2 notebooks for $ 0.60 as unit rate is $ 0.30 per notebook

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
