Answer:
1)

Step-by-step explanation:
N/A
also what is your inequality problem
Total was x
subtract 36.25 amount of money and you have -14.75 left
You can write this
x - 36.25 = -14.75
add 36.25 to both sides
x = -14.75 + 36.25
Solve by combining like terms
x = 21.5
You had $21.5 on your account before you withdrew $36.25 and had a balance of -$14.75 left.
Hope this helps!
New pump = (Old Pump * Total) / (Old Pump - Total)
New pump = (14 * 6) / (14 -6)
New pump = (84) / (8)
New Pump = 10.5 hours
This is an arithmetic sequence with common difference 4.3
The rule is an = an-1 + 4.3 where a1 = -22.7
Just multiply them together and you'll get 58,466.
