Step-by-step explanation:

A translation is a shift side to side or up and down

A reflection is a mirror image across a line

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

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
