Answer:
$5.76
Explanation:
There are 16 US tablespoons inside a cup.
Since there are 2 pies, each needing 1/2 a cup, we can just class this as a full cup, as it is equivalent.
Since each lemon yields 2 tablespoons, we can do the following equation:
16/2=8
This gives us 8 lemons.
8 x 0.72 = 5.76
Therefore, this should cost $5.76
Hope this helps :D
