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

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

The solution is given in the image below

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

30% of 420 are first year students

first year students = (30/100 )*420

=126 students

Student who are not in first year = 420-126

=294 students  

(​1 or 7) ; number of possible outcome = 2

(a, e,​ i, o, or​ u) ; number of possible outcome = 5

So,

Number of possible outcomes = 2 x 5

Number of possible outcome =10

The answer is in the image 

Given,

Area of base = 6ft

Volume = 15ft

We know,

Volume = area of base * height

15 = 6 * height   

height = 15/6

   = 2.5ft   

Different mustangs that can be created are = 5 * 3 * 2

                                                                      = 30

30 different mustangs can be created
