Step-by-step explanation:
Let's first calculate the total cost of the chocolate fudge:
6 pounds = 12 half-pounds (since 1 pound = 2 half-pounds)
Cost = 12 half-pounds x $2.85 per half-pound
= $34.20
Kyle received $5.80 in change, so the amount he paid is:
Amount paid = Total cost + Change
= $34.20 + $5.80
= $40.00
Therefore, Kyle gave the cashier $40.00.
