Answer: 78
Explanation:
From the question, 6 ounces of dough and 4 ounces of sauce will be needed for each person at the party. This means each person will use 4+6 = 10 ounces. Since 130 ounces were bought, it means that there are: (130/10) = 13 people.
Let the number of ounces of dough be x.
Since 6 ounces of dough are used and there are 13 people. This will be: = 13 × 6 =x
x = 78
