The answer to the question is it would add twenty seven every two times it goes up
Convert gal to cup
16 cups = 1 gallon
or 16 cuos per gallon
or 16 cups/gallon
1.5 gallons × 16 cups/gallon = 24 cups
(gallons cancel out)
The constant of proportionality is <em>4 .</em>
The equation is [ <em>Height = (4) times (Days)</em> ] .
When the sunflower is 60cm tall, 60 = (4) times (Days).
Divide each side of the equation by 4: <em>15 = Days</em>
