she went over by one over three of a cup.
she needs to add one over three of a cup.
she needs to add one over six of a cup.
she went over by one over six of a cup.

Option 4 - She went over by one over six of a cup.

Step-by-step explanation:

Given : Laura is baking a cake. The recipe says that she has to mix 64 grams of chocolate powder into the flour.

Laura knows that 1 cup of that particular chocolate powder has a mass of 128 grams. She added two over three of a cup of chocolate powder to the flour.

To find : Should Laura add more chocolate powder to make the exact recipe, or did she go over and by what amount?

Solution :

The required mass of chocolate powder in two over three of a cup of chocolate powder with mass 128 grams.

Multiply 128 by  two over three

So, Laura added more chocolate powder to make the exact recipe

Now, The amount of chocolate Laura added too much to make the exact recipe

Subtract 64 grams from 85.33 grams

The amount she needs to add.

Now, 64 grams represent

of a cup of chocolate

She added 2/3 of a cup of chocolate powder to the flour.

If we compare:

Then, she went over by:

Therefore, Option 4 is correct.

She went over by one over six of a cup.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

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
