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