Sagot :

Answer: $6.67

Step-by-step explanation:

A volleyball camp chargers $150 per camper for 10 campers. The cost for each camper will be:

= $150/10

= $15

When a team brings 15 campers, the rate is reduced to $125 per camper. The cost for each camper will be:

= $125/15

= $8.33

The rate of change in cost per camper will be:

= $15 - $8.33

= $6.67
