Ms. Chen is planning to take her camp group on a field trip to Pottery Bayou where each person will create her own piece of art
erica [24]

Answer:

1. C=21x.

2. C=(8x+104).

Step-by-step explanation:

Let the number of people in the group be x. Denote the total cost as C.

1. If the regular cost is $21 per person, then the total regular cost for x people is C=21x.

2. If the special cost is $8 per person, then the total special cost for x people is \$8x. There is an additional $104 fee for a private room, thus the total special cost is C=(8x+104).

Mary repairs microwaves. her revenue is modeled by the function r(h)=20+30h for every h hours she spends repairing microwaves. h
MrRa [10]
Answer: After 5 hours, Mary will be at the break even point.

To answer this question, we need to find the time when the cost equals the revenue.

Therefore, set our equations equal to each other and solve.

20 + 30h = 10h^2 - 80
0 = 10h^2 - 30h - 100
0 = h^2 - 3h - 10
0 = (h - 5)(h + 2)

Our solutions are h = 5 or h = -2. Only 5 hours makes sense in the context of this problem.

Kaylis [27]

Answer:

6

Step-by-step explanation:

Hello, we can use the Remainder Theorem, so the remainder is P(-1)

P(-1)=3+2+2-1=6
