Hey there!!

The answer - ( c )

scientific notation - the number shall be between 1 and 10 and 10 shall be raised to a power

4500

This can be written as

4.5 × 1000

1000 = 10³

so,

scientific notation = 4.5 × 10³

Hope my answer helps!

i would need to see the dot plot : )

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
