48 stars

Step-by-step explanation:

This is an equation where you have to find an equivalent fraction.

So, it is given to us that 12/30 = something (x) /120.

So, what happened to 30 to make it 120 in the respective denominators? It was multiplied by 4.

So, that’s what you do to the numerator, multiply it by 4.

So 12 x 4 = 48.

Now put it back as a fraction 12/30 = 48/120

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
