Mrs. Jean said that 4/12 of the test items are multiple choice, 5/12 or short answer and the rest are matching. What fraction of these items are either multiple choice or short answer

3/4

Step-by-step explanation:

THE fraction of these items are either multiple choice or short answer would be the sum of the fractions of the multiple choice and short answer

4/12 + 5 / 12 = 9/12

to simplify , divide both numerator and denominator by 3

3/4

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
