Answer:
The correct answers are the following:
A) P=12n-275
B) 124
C) Decrease by $100
Step-by-step explanation:
A) P=12n-275 - Each person (n) pays $12, then the cost/expense ($275) is subtracted from the income to get the profit.
B) 1,213=12n-275 - Plug in the value for P ($1,213).
1,488=12n - Add $275 to both sides.
124=n - Divide both sides by $12.
n=124 - This the number (n) of people that attended.
C) P=12n-375 - Change the value for expense to $375.
P=12(124)-375 - Plug in the value for n (124).
P=1488-375 - Simplify and find the difference.
P=1,113 - This is your profit.
1,113-1,213=-100 - $100 reduction/decrease of profit (or -$100 to profit)
Hope this helps!
