363 gallons of water is in Tank A
<em><u>Solution:</u></em>
Water tank A has a capacity of 550 gallons and is 66% full
Let, w = 550
p = 66 % = 0.66
The percent equation is: a = p . w
where,
"a" is the gallons of water in Tank A
p is the percent in fraction or decimal form
w is the capacity of tank A
Therefore,
Thus 363 gallons of water is in Tank A
