Question

A pool filling service charges $2.00 per cubic meter of water for the first 300 cubic meters and $1.50 per cubic meter of water after that. At this rate, how much would it cost to have the service fill a rectangular pool of uniform depth that is 2 meters deep, 20 meters long, and 15 meters wide?

Answer 1

First find the volume of the pool...2x20215=600cubic meters.

$2x(300)=$600
$1.50x(600-300)=$450

600+450=$.1050

Answer 2

The volume of the pool is 2*20*15 or 600 cubic meters. Thus it would cost $2*300 for the first 300 and $1.5*300 for the rest.
This comes out to $600+$450 or $1050

Answer 3

The volume of the pool is incubic meters

V= l*w*h = 20*15*2 = 600 m^3 m^3 = cubic meters

so you use 300 m^3 at $ 2 and 300 at $1.5

price P = 300*2+300*1.5 = 1050 $

Answer 4

Vol. of water = 2*20*15
= 600 cm3
300 * 2 = $600

1.50 * 300 = $450

Total Cost = $600 + $450

It cost $1050 to fill up the pool

Answer 5

volume = 2*20*15
= 600

for 1st 300 = 2*300
= 600
for 2nd 300 = 1.5*300
= 450
total = 600+450
= $1050

Answer 6

first 300 cubic meters cost $600
next 300 cubic meters cost $450
total cost $ 1,050

Answer 7

$1050 ($300X2 + $300X1.5)
