Darby solved the equation correctly but does not know what the final line means. In the box below, explain what Darby's calculations Indicate.

3(1/2x + 9) = x-12+ 1/2x
3(1/2x) + 3(9) = x+ 1/2x-12
3/2x + 27 = (1 + 1/2)x - 12
3/2x + 27 = 1 1/2x - 12
3/2x - 3/2x + 27 = 1 1/2x - 3/2x - 12
27= -12

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

the correct answer is $7.38
