Answer: 349
Step-by-step explanation:
Using the arithmetic sequence, it would add up to be 349
You input the values and the equation would end up as
-5 = -3/2 (6) + b
You use y = mx + b
Y is -5
M is the slope = -3/2
X is 6
B is the y intercept but that is not given
Find out how many liters are used in the old toilet in a year;
4×27= 108 l (in a day)
365×108= 39420 liters (in a year)
Find out how many liters are used in the new toilet;
4×6=24 (in a day)
24×365=8760 l (in a year)
Find the water saved; 39420-8760
= 30660 l saved.
Hope I helped :)
