Meredith is purchasing a new toilet for her home. Toilet A costs $149 and uses approximately 380 gallons of water per month. Toilet B costs $169 and uses
approximately 300 gallons of water per month. Water costs $2.75 per 1000 gallons.
Part A: Write a system of equations that models this situation.
A. A = 149 +2.75 300t
C. A = 149 +2.75 0.3.t
B= 169 +2.75 -380t
B = 169 +2.75 0.38.t
B. A= 149 +2.75 380-t
D. A = 149 +2.75 -0.38.t
B = 169 +2.75 300-t
B = 169 +2.75 -0.3.t
Part B: How many months will it take for Toilet B to be more cost effective?
