If two quantities x and y are in direct proportion, then .

x/ y = k

Step-by-step explanation:

It can also be written in forms like-

x= ky

y= x/ k

x/y = k

(here k is constant )

could you reply to this with the question so i can ?

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
