To find the cost of a dozen ears of corn, we first need to determine the price of one ear of corn from the given rate.
The rate for corn is 5 ears for $1.30, so the cost per ear can be calculated as follows:
\[
\text{Cost per ear} = \frac{1.30}{5} = 0.26 \text{ dollars per ear}
\]
Now, to find the cost of a dozen ears (12 ears):
\[
\text{Cost for 12 ears} = 12 \times 0.26 = 3.12 \text{ dollars}
\]
Thus, the cost for a dozen ears of corn is **$3.12**.
