Answer:
$3.50/donut
Step-by-step explanation:
Since Rosena bought an 8-pack of donuts for $28.00, we can say that the price of $28.00 corresponds with this pack.
The unit rate represents the price per donut, assuming a constant proportion.
The pack that Rosena bought contains 8 donuts. Therefore, to find the price of one donut, divide the price that corresponds with the 8-donut pack by 8, because [tex]8\div 8=1[/tex].
The price of the 8-pack of donuts was [tex]\$28.00[/tex]. Diving by 8, we have:
[tex]\frac{\$28.00}{8}=\boxed{\$3.50}[/tex]
Therefore, the unit rate for the donuts is $3.50/donut.
