Dana said that speed, s, could be either an independent or dependent variable. Write a situation where speed, s, is an independent variable. Then write a situation where speed, s, is a dependent variable.

As dependent variable;

speed = distance/time

As independent variable

distance = speed * time

Step-by-step explanation:

When we say dependent variable, we mean that the value of the speed depends on some values.

When we say independent, we mean the value of some quantities is dependent on the speed.

As dependent variable;

speed = distance/time

As independent variable

distance = speed * time

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
