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 $C=(8x+104).$
