step 2
<em>Find out the unit rate of a travel size tube of toothpaste</em>
we know that
To find out the unit rate, divide the total cost by the total weight
so

The unit rate
represent the 100%
so by proportion
Find out what percentage represent the difference ($0.83-$0.78=$0.05 per ounce)

therefore
The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy
Answer:

h
h
t = total time
g = job = 1 (clean the gutters)

h
Then, both together paint
of gutters for each hour.
