Question

A manatee eats the equivalent of about 12% of its body weight each day. Write an equation that represents the amount y (in pounds) of food a manatee eats each day for its weight x. Identify the independent and dependent variables.

Answer 1

Y is the amount of food that a manatee eats each day:
the weight is X 
12% or its weight is   X x 12 /100= 12x /100=3x/25
so the equation is y= 3x/25
the dependent variable is y (it depends to the value of x)
and the independent is x
