What is the product of -4 1/2 and 2 1/2and i need the answer is a mixed number

The product would be -11 1/4.

BECAUSE

You convert mixed numbers to fraction

−9/2 × 5/2

Multiply the fraction and that would give you -45/5

By simplifying -45/5, the answer is -11 1/4

HOPE THIS HELPS :)

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
