zepelin [54]

Answer:

Number of guests = 13

Sauce = 52 ounces

Dough = 78 ounces

Step-by-step explanation:

you are having a pizza making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including myself the host) Once you have a total count of guests you have exactly the amount needed for ingredients. the dough and sauce that I have is 130 ounces all together. How many ounces of dough did I buy? Explain How many ounces of sauce did I buy? Explain How many guests are coming to the party? Explain

Dough = 6 ounces

Suase = 4 ounces

Dough + sauce = 6 + 4 = 10

Let x = total number of guests

Dough ingredients + sauce ingredients = 130

10x = 130

Divide both sides by 10

x = 130/10

= 13

x = 13

Number of guests = 13

Total ounces of dough = 6 ounces × 13 guests

= 78 ounces of dough

Total ounces of sauce = 4 ounces × 13 guests

= 52 ounces of sauce

Therefore,

Number of guests = 13

Sauce = 52 ounces

Dough = 78 ounces
