Question

Identify the independent and dependent variable:The equation t=12p+12 gives the total cost t (in dollars) of a meal with a tip of p percent (in decimal form)

Answer 1

t=12p+12
12p+12=t
_. _
12. 12 1p=t

Answer 2

dependent variable = t

independent variable = p

Explanation:

Hi, in the equation t=12p+12, p is the independent variable, because is an input value.

t is the dependent variable, because is the output value, it depends of the input value.

For example if p =1, t=24

t(1) =12(1) +12

t(1) = 12+12 =24

But if p=0; t=12

t (0) = 12(0) +12 =12

We can see how the value of t varies as the value of p changes.

in thers of the statement, the total cost of the meal (t) depends on the tip percentage (p).
