Answer:
the ounces of dough did you buy is 78
Explanation:
The number of dough ounces that should be buy is given below:
Given that 
There is a requirement of 6 dough ounces and 4 sauce ounces
So for each person it would be 
= 4 + 6 
= 10
Now the total ounces bought is 130 
So, the number of people used 
= 130 ÷ 10 ounces
= 13 people 
Now let us assume the number of dough ounces be x 
Now if there is 6 dough ounces and there are 13 people
So, the total dough ounces purchased is 
x = 6 × 13
= 78
 Hence, the ounces of dough did you buy is 78
