Rain is flowing into two containers at
different rates. The figure below shows the
volume of water in each container at
different times.
What is the difference in the rate of change between the two containers?

A.1/5 gallon per minute
B.3/5 gallon per minute
C.5/2 gallon per minute
D.15/2 gallon per minute

Given:

Volume of water in each container.

To find:

Difference in the rate of change.

Solution:

Take any two points on container 1.

Let the points are (10, 2) and (20, 4).

Rate of change for container 1 is .

Take any two points on container 2.

Let the points are (5, 2) and (10, 4).

Rate of change for container 2 is .

Difference =

The difference in the rate of change between the two containers is gallon per minute.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

c is the correct answer
