Answer:
Option B. These customers use at least 4,970 gallons but no more than 8,970 gallons of water per month
Step-by-step explanation:
Let
x -----> the number of gallons of water, used by customers
we know that
The system of inequalities that represent this situation is
[tex]10.15+0.005x\geq 35[/tex] -----> inequality A
[tex]10.15+0.005x\leq 55[/tex] -----> inequality B
Solve the inequality A
subtract 10.15 both sides
[tex]0.005x\geq 35-10.15[/tex]
[tex]0.005x\geq 24.85[/tex]
divide by 0.005 both sides
[tex]x\geq 4,970\ gal[/tex]
Solve the inequality B
subtract 10.15 both sides
[tex]0.005x\leq 55-10.15[/tex]
[tex]0.005x\leq 44.85[/tex]
divide by 0.005 both sides
[tex]x\leq 8,970\ gal[/tex]
therefore
These customers use at least 4,970 gallons but no more than 8,970 gallons of water per month
