The set of ordered pairs represents a function. Write a rule that represents the function. (1,8),(2,64),(3,216),(4,512)

Step-by-step explanation:

I hope you can follow what I have shown.  What is happening is the the y value in each ordered pair is the cube of 2 times the x value

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
