A spaghetti dinner fundraiser served 500 people and charged $7 for adults and $4.50 for children. use x to represent the number of adults served and write and expression to show how much money was raised. then simplify the expression.

Let x be the number of adults.

adult = x

children = 500 - x

total fund raised from the adult = $7x

Total fund raised from the children = $4.5 (500 - x)

Total fund raised = 7x + 4.5 (500 - x)

7x + 4.5 (500 - x) = 7x + 2250 - 4.5x

= 2.5x + 2250

Ans: Total fund raised = $ (2.5x + 2250)
