Let’s check out your problem:

Mikayla is the communications director for a politician and has recommended that a total of 41 speaking events are given by the politician before election day. Each speaking event is either a formal speech or an informal talk. Mikayla also recommends a total of 9 more formal speeches than informal talks. Which of the following systems of equations can be used to find out the number of formal speeches 
s versus the number of informal talks 
t ?
Choose 1 answer:
(A) 
t=s+9

s+t=41
(B) 
t=s+9

s=t-41
(c) 
s=t+9

s+t=41

Q. Mikayla is the communications director for a politician and has recommended that a total of 4141 speaking events are given by the politician before election day. Each speaking event is either a formal speech or an informal talk. Mikayla also recommends a total of 99 more formal speeches than informal talks. Which of the following systems of equations can be used to find out the number of formal speeches s s versus the number of informal talks t t ?\newlineChoose 11 answer:\newline(A) t=s+9 t=s+9 \newlines+t=41 s+t=41 \newline(B) t=s+9 t=s+9 \newlines=t41 s=t-41 \newline(C) s=t+9 s=t+9 \newlines+t=41 s+t=41
  1. Define Variables: Define the variables based on the information given.\newlineLet ss be the number of formal speeches.\newlineLet tt be the number of informal talks.\newlineMikayla recommends 99 more formal speeches than informal talks, which can be represented as s=t+9s = t + 9.\newlineThe total number of speaking events is 4141, which can be represented as s+t=41s + t = 41.
  2. Match Equations: Determine which system of equations matches the information given.\newlineOption (A) states:\newlinet=s+9t = s + 9\newlines+t=41s + t = 41\newlineThis does not match the information given because it suggests there are 99 more informal talks than formal speeches, which is the opposite of what is stated.\newlineOption (B) states:\newlinet=s+9t = s + 9\newlines=t41s = t - 41\newlineThis is incorrect because the second equation does not make sense in the context of the problem. It suggests that the number of formal speeches is 4141 less than the number of informal talks, which is not possible since the total number of events is 4141.\newlineOption (C) states:\newlines=t+9s = t + 9\newlines+t=41s + t = 41\newlineThis matches the information given, with the first equation representing 99 more formal speeches than informal talks and the second equation representing the total number of speaking events.
  3. Choose Correct Equations: Choose the correct system of equations based on the analysis in Step 22.\newlineThe correct system of equations is Option (C):\newlines=t+9s = t + 9\newlines+t=41s + t = 41
