At the beginning of the day, stock xyz opened at $6.25. at the end of the day, it closed at $5.95. what is the rate of change of stock xyz?

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

ummm seems that u didnt post the attachement !
