Final answer:
The total weight of the 8 baseball doughnuts is 45 ounces, calculated by multiplying the weight of one doughnut (5.625 ounces) by the number of doughnuts (8).
Step-by-step explanation:
The total weight of the baseball doughnuts can be found by multiplying the weight of a single doughnut by the number of doughnuts brought to the game. As each doughnut weighs 5 ⅗ ounces (which is 5.625 ounces in decimal form) and they bring 8 doughnuts to away games, the calculation is as follows:
5.625 ounces/doughnut × 8 doughnuts = 45 ounces
Therefore, the total weight of the 8 baseball doughnuts is 45 ounces.
