A volleyball camp chargers $150 per camper for 10 campers. When a team brings 15 campers, the rate is reduced to $125 per camper. What is the rate of change in cost per camper ?

$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

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
