Marisol is incorrct Diego and Andrea paid the same amount for each ticket . This is because 46.5 times 3 equals to 139.50 so each ticket cost the same amount of money.Since Andrea paid for 9 tickets and Diego for 3 you multiply the cost by 3 so you get the answer and see if its less or greater than Andreas aount of money.

Answer:

D Antenna #4

Step-by-step explanation:

As per given graph we can write the function

the intercept is zero, as x=0, y=0

at x=2, y=30 ⇒ 30= 2*15
at x=4, y=60 ⇒ 60= 4*15

The slope is 15, so the function is

y=15x

And the function for the antenna revolving at twice the rate would be

y=30x

Comparing data in given tables we can see it is D Antenna #4

x= 22 ⇒ y= 22*30= 660
x=24 ⇒ y= 24*30= 720
