Answer 1

20000 gallons of water are in pool

Solution:

Given that To maintain an acceptable level of chlorine in your pool you add 1.4 gallons of chlorine

This is 0.007℅ of the amount of water in your pool

To find: gallons of water are in your pool

From given question,

1.4 gallons of chlorine = 0.007℅ of the amount of water in your pool

Let "x" be the amount of water in your pool

Therefore,

1.4 = 0.007 % of x

$1.4 = \frac{0.007}{100} \times x\\\\1.4 = 0.00007 \times x\\\\x = \frac{1.4}{0.00007}\\\\x = 20000$

Thus 20000 gallons of water are in pool
