Answer:
The model represents the equation
-3x + 6 = 4x -8
Start by subtracting 6 from both sides.
-3x + 6 (-6) = 4x - 8 (-6)
-3x = 4x - 14
Subtract 4x from both sides
-3x - 4x = 4x - 4x - 14
-7x = -14
x = -14/-7
x = 2

Complete question :
A pool holds 1440 cubic feet of water, the city charges $1.75 per cubic meter of water used.
How much will it cost to fill the pool?
Answer:
$71.36
Step-by-step explanation:
Amount charged per cubic meter = $1. 75
Total volume of pool = 1440 ft^3
Using the conversion unit chart :
1 cubic meter = 35.3147 cubic foot
Then we can express the capacity of water held by the pool in cubic metre.
If 1 cubic meter = 35.3147 cubic foot
Then ;
y cubic meter = 1440 cubic foot
y = 1440/35.3147
y = 40.776220 cubic meter
Thus;
Cost of filling the pool will be;
$1.75 × 40.776220
= $71.358386
= $71.36
