Santa's Wonderland is an extravagant holiday light display that is open from early November through January each year. The entry fee is $15 per vehicle for up to and including 5 people, with an additional $1.50 for each person over 5. Express this information as a piecewise function of x, where x represents the number of people in the vehicle.

The expression

Y(x)= 15(v)+1.5(x)

Step-by-step explanation:

The entry fee is $15 per vehicle for up to and including 5 people, with an additional $1.50 for each person over 5.

Let the entrance fee be Y

Let the number of vehicle be V

Let X be the number of people more than 5

The expression

Y(x)= 15(v)+1.5(x)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

the answer is d

hope this
