Final answer:
Tyrone needs 136 ounces of cookie dough to make a four-ounce cookie for each of his 34 guests.
Step-by-step explanation:
Tyrone is serving 34 guests and wants to make one four-ounce cookie for each guest. The original recipe makes 68 cookies at four ounces each. To find the total amount of cookie dough Tyrone needs, we multiply the number of guests by the weight of each cookie.
Here's the calculation:
- Number of guests: 34
- Ounces per cookie: 4
- Total ounces of cookie dough needed: 34 guests Ă— 4 ounces per cookie = 136 ounces.
Therefore, Tyrone needs 136 ounces of cookie dough to serve all his guests.
