Answer:

$172\frac{1}{2}$ gallons

Step-by-step explanation:

Considering she waters her plants with 25 1/2 gallons i.e 51/2

and with the new system, she does it with 19 3/4 i.e 79/4

taking the difference:

$\frac{51}{2} - \frac{70}{4}$ = $\frac{23}{4}$ gallons per day

For 30 days:

30 x $\frac{23}{4}$ = 172.5 or $172\frac{1}{2}$ gallons
