The pool at the hotel where gabriel is staying is symmetrical and shaped like the letter “w” below. the bottom surface of the pool is flat and needs new tile. if each tile covers 1/2 of a square yard and costs $3, what is the cost of the tiles to retile the bottom of the pool? 10,10,20 is the numbers you multiply i think answers below $1,500 $4,500 $10,800 $13,500

The cost of the tiles to re-tile the bottom of the pool is $3000

Step-by-step explanation:

* Lets use the attached figure to solve the problem

- The pool is symmetrical and shaped like the letter “W” as the

 attached figure

- Each tile covers 1/2 of a square yard and costs $3

- To find the area of the pool we consider the pool consists of two

  rectangles with dimensions 20 yards and 10 yards and a square of

  side 10 yards

∵ The area of the rectangle is the product of the two dimensions

∵ The area of the square is side × side

∴ The area of the pool = 20 × 10 + 20 × 10 + 10 × 10

∴ The area of the pool = 200 + 200 + 100 = 500 yard²

- Each tile covers 1/2 yard²

∴ The number of tiles = area pool ÷ area tile

∴ The number of tiles = 500 ÷ 1/2 = 1000 tiles

- The cost of each tile is $3

∵ The cost of the tiles = number of tiles × cost of 1 tile

∴ The cost of the tiles = 1000 × 3 = 3000

* The cost of the tiles to re-tile the bottom of the pool is $3000

step-by-step explanation:

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
