each morning a gardener uses 24 3/4 gallons of water from a barrel. each afternoon, she adds 15 1/4 gallons of water to the barr

Nimfa-mama [501]

Answer:

$47\frac {1}{2}\ gallons$

Step-by-step explanation:

Assuming that the tank is only for agricultural use, also no significant leakages then at the end of the day, the amount consumed will be equivalent to $24\frac {3}{4}-\ 15\frac {1}{4}=9\frac {1}{2}$

For 5 days, the quantity reduces by 9.5*5=47.5 gallons

Therefore, the barrel would have changed by $47\frac {1}{2}\ gallons$
