Total cost:
2 monitors x $25.00 = $50.00
4 cases x $15.00 = $60.00
5 memory modules x $20.00 = $100.00
Total cost = $50.00 + $60.00 + $100.00 = $210.00
Revenue from sales:
2 monitors x $88.00 = $176.00
4 cases x $24.00 = $96.00
5 memory modules x $55.00 = $275.00
Total revenue = $176.00 + $96.00 + $275.00 = $547.00
Total profit:
Total revenue - Total cost = $547.00 - $210.00 = $337.00
Therefore, Morty's total cost for the items he purchased was $210.00, his revenue from the sale of the items was $547.00, and his total profit was $337.00.
