A grocery store sells a bag of 4 oranges for $2.84. How much would it cost for 5 oranges?

To find the cost of 5 oranges, we first determine the cost per orange.

1. The cost of 4 oranges is $2.84.
2. The cost of one orange is:

\[
\text{Cost per orange} = \frac{2.84}{4} = 0.71
\]

3. Now, we multiply the cost per orange by 5 to find the cost of 5 oranges:

\[
\text{Cost of 5 oranges} = 0.71 \times 5 = 3.55
\]

Thus, the cost of 5 oranges is **$3.55**.
