Answer:
8192 cases/week
Explanation:
We know that one driver makes 64 deliveries per week. We can write that as 64 deliveries/week.
We can write "For each delivery, he delivers 74 cases of dry goods and 54 cases of canned goods" as 74 cases dry food/delivery and 54 cases canned good/delivery. This is a total of 128 cases food/delivery.
To answer how many cases in total for 1 week, we can multiply as follows, taking care that the units will cancel in a way that leaves just cases/week as the answer.
(64 deliveries/week)(128 cases food/delivery) = 8192 cases/week
