Answer:
b.332.2
Step-by-step explanation:
Use a proportion.
Let A = water used in household A.
Let B = water used in household B.
A to B = 13 to 5
A = 260 gal
260 to B = 13 to 5
260/B = 13/5
13B = 5 * 260
B = 100
A + B = 260 + 100 = 360
The total is 360 gallons.
-3 is further away from 0 because if you graph it on a number line, it will show that -3 is one unit further from 0 than -2.
