36

Step-by-step explanation:

Any number on top, like 6^2 is multiply the number by itself accordingly to the number on top. For example, if it is 6 to the 4th, then you multiply 6 by itself 4 times, and you will get 1296. Squaring is a number multiplying to itself according to the exponet.

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

good luck on your studies! : )
