Carmen needs 1,100 to purchase a computer she has saved 1/3 of the money so far this year she will save the remaining amount by the end of the year about how much will she have saved at the end of the year

733.33$

Step-by-step explanation:

In this case, I'll assume that Carmen have the 1/3 at the beggining of the year, and we don't know how much she save every month. However we can still do this, because we already know how much she has saved by now, so, that's a clue of the remaining amount.

You can do this in 2 ways:

First method:

Let's calculate the 2/3 remaining, of this way:

1100 * 2/3 = 2200/3 = 733.33$

Second method:

Let's see how much is 1/3 of 1100, and then, do the difference between this amount and the total:

1100 * 1/3 = 366.67

1100 - 366.67 = 733.33$

And that's the amount that she would save by the end of the year (without counting the 366.67$ that she already have saved).
