Given figure abcd ~ figure wxyz, what is the value of k?

You can use ratio and proportion in this problem.

Segment DC / Segment CB = Segment ZY / Segment YX

2.3m / 4.2m = k / 8.4m

K = 8.4 (2.3 / 4.2)

K = 23/5 or 4.6 m 

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
