Ms. Jones showed her students the prime factorization of 90. What factor is missing? 2 . (3 to 2nd power) . ? (Another look 2x (3 to 2nd power) x?) Fill in blank with correct factor. Hint, you can also create a factor tree of 90 to find the answer. A.9

First, you should find the ratio of how much more sugar Maggie added.  Set it up like this:

6x = 9

x = 9/6

x = 3/2

We now know that Maggie added 3/2 more sugar than she was supposed to.  To keep consistent with recipe, we have to multiply this ratio with the amount the recipe calls for:

3/2(2) = 3

Maggie should add 3 tablespoons of mustard.
