The expression for the cost of the ABC Book Club is 2x + 40. The expression for the cost of the Easy Book Club is 3x + 35. To find when the total charge for both book clubs is equal, the two expressions must equal each other. (x = the number of books read)
2x + 40 = 3x + 35
Subtract 35 from both sides.
2x + 5 = 3x
Subtract 2x from both sides.
5 = x
So, the total charge for each club is equal when 5 books are read.
Fractions and decimals are related in a very close way. Ways such as they are both representing a whole number.
for example
1/2 , 0.5 , 50%
all three numbers have the same value but are expressed in a different format. all three represent the same whole number.
another example would be
1/4 , 0.25 , 25%
hopefully this helped. and or makes sense.

C = 21.99
Answer: 4 seconds
Step-by-step explanation:
Given: The function 
can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get
Put h'(t)=0
Also, 
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
