-310+135=-175
30 22
20 18
(im sorry in advance if you get it wrong, but im sure you'll get it right)
4y=7x

so, x+y=22
x=(22-y)
by substitute (22-y) for x in the first equation.
Answer:
B. a decrease in their water bill of $3.16.
Step-by-step explanation:
Monthly service charge =$10.10
Volume charge = $1.58 for every 100 cubic feet of water.

.
Volume Charge per
of water = $1.58
Therefore: Volume Charge for
of water = 2 X $1.58=$3.16
Therefore, the Johnson family can expect a decrease in their water bill of $3.16.
