If a store sells apples for $2 each, how much will 15 apples cost?

To determine the total cost of 15 apples at a price of $2 each, you can simply multiply the price per apple by the quantity of apples.

Calculating this gives: $2 per apple × 15 apples = $30.

This shows that the total cost for 15 apples is indeed $30, making it the correct answer. The other options reflect incorrect multiplication or addition of prices that do not align with the given price per apple. For instance, options such as $25 or $32 might stem from miscalculation or misinterpretation of the multiplication involving the number of apples and their cost.
