Answer:
A : 3x + 8 = 41
B : x = 11
Explanation:
For this problem, there are two parts, so I am going to explain A first. So we know that the final cost is going to equal to 41. There are two costs, one of which we know and one of which we don't. The cost we do know of is the special group fee, which is 8. Now we know something plus 8 is going to equal to 41. The second cost is the cost per person, but we don't know how many people there are, so what we do instead is say the is of people x. If it costs the 3 dollars per person, the second cost is 3x. Now we know that
3x + 8 = 41, and that's your answer to part A. For part B, all we have to do is solve it. To do that, the first thing we are going to do is isolate the variable by subtracting 8 form both sides. Now we end up with 3x = 33. To finish solving, we just have to divide both sides by three so we end up with x. Once we do that, we get x = 11, and that's your answer to B. I hope this was helpful and you learned something form this.
