If your asking what 9B coefficient is it's B
Answer:
Revenue and Expense = $230
No. of attendees: 10
Step-by-step explanation:
Let n be the no. of attendees
Expense = 50 + 18n
Revenue = 23n
Break even when:
50 + 18n = 23n
50 = 5n
n = 10
23n = 230
8 in 2.408 is closer to 10, so you round 2.408 to 2.41
I think the answer is 2 and -15. Because 2 times - 15 is -30 and 2 and -15 can be added to -1.
