To find out how much more baking powder Erica had yesterday, we need to subtract the amount she has now from the amount she had yesterday.

First, we need to convert the mixed numbers into improper fractions.

7 2/3 = 23/3 (because 7*3 + 2 = 23)
1 1/2 = 3/2 (because 1*2 + 1 = 3)

Now, subtract the smaller fraction from the larger one:

23/3 - 3/2 = 46/6 - 9/6 = 37/6

To convert this back into a mixed number, divide the numerator by the denominator:

37 ÷ 6 = 6 remainder 1

So, Erica had 6 1/6 more boxes of baking powder yesterday.
