Final answer:
After converting 350 pounds of sirloin steak to 5600 ounces (using the conversion rate of 1 pound = 16 ounces), we divide by the portion size of 10 ounces per dinner to find that the chef can serve 560 sirloin steak dinners.
Step-by-step explanation:
To determine how many sirloin steak dinners can be served, we first need to convert the total pounds of steak to ounces, since the portions are measured in ounces. The first step is to use the conversion rate: 1 pound = 16 ounces. Multiplying the number of pounds by 16 gives us the total number of ounces available.
350 pounds × 16 ounces/pound = 5600 ounces of sirloin steak on hand.
Next, we need to divide the total number of ounces of sirloin steak by the portion size, which is 10 ounces per dinner.
5600 ounces ÷ 10 ounces/dinner = 560 dinners.
Therefore, the chef can serve 560 sirloin steak dinners. The answer is rounded to the nearest whole number, as requested.
