Prove that v e n with 1, we have 202 + 7x + 4 > 25. (b) prove that there exists @ € q and o z such that (2744) e z. (hint: 2744 = 23.73)

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
