Final answer:
To find out how much dough and sauce you bought and how many guests are coming to your pizza party, you can use some simple calculations.
Step-by-step explanation:
To find out how many ounces of dough you bought, you need to subtract the weight of the sauce from the total weight.
So, 130 ounces - 4 ounces for each person = remaining weight of the dough.
Since you need 6 ounces of dough for yourself, you subtract 6 ounces from the remaining weight to find out the amount of dough you bought.
To find out how many ounces of sauce you bought, you need to multiply the number of guests (including yourself) by 4 ounces.
To find out how many guests are coming, you need to divide the weight of the sauce by 4 ounces.
