You may use model to visualize. Here are some explanations in words:

Since the question states that each shirt cost 4 times as much as a pair of shorts, we can infer that: The cost of 1 shirt is 4 unit while the cost of 1 pair of shorts is 1unit.

As such, 5 shirts is 4units x5, equivalent to 20 units. 8 pair shorts is 1unit x8, equivalent to 8 units. Total cost of 5 shirts and 8 shorts is 20 units + 8 units, equivalent to 28 units.

Since the question states that the total cost of 5 shirts and 8 pair of shorts is $336, we can infer that 28 units = $336.

To find the cost of 1 shirt, we need to find 4 units. To do that, we divide $336 by 28units, then multiply by 4 units (refer to the workings in my picture)

Hope that helps! :)
