A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
Answer:
The total cost
in dollars of going to the baseball game for
people of a family can be given as:

Step-by-step explanation:
Given:
At a baseball game:
Cost of car parking = $5
Cost per ticket = $21
To write an equation in the form of
representing the total cost of going to the baseball game.
Solution:
The total number of people in the family is = 
Using unitary method to find the cost of tickets for
persons.
If 1 ticket costs = $21
<em>Then,
tickets will cost in dollars</em><em> = </em>
Fixed rate for car parking = $5
Thus, the total cost
in dollars of going to the baseball game for
people of a family can be given as:
