Given:
• Each person needs 6 ounces of dough and 4 ounces of sauce.
,
• Total of 130 ounces of dough and sauce all together.
Let x be the number of persons.
So, the equation is,
6x+4x=130
Solving the equation, we get
[tex]\begin{gathered} 6x+4x=130 \\ 10x=130 \\ x=13 \end{gathered}[/tex]
So, there are 13 persons.
a) To find the number of ounces of dough were used at the party:
Since, 6x is the number of ounces of dough were used at the party.
So,
[tex]13\times6=78\text{ ounces}[/tex]
Hence, the number of ounces of dough were used at the party is 78 ounces.
b) To find the number of ounces of sauce were used at the party:
Since, 4x is the number of ounces of sauce were used at the party.
So,
[tex]13\times4=52\text{ ounces}[/tex]
Hence, the number of ounces of sauce were used at the party is 52 ounces.
c) To find the number of people in the party:
Number of people in the party is x=13.
