I don't know if this is correct but id say

What is the mean price per pound for each type of produce?

IrinaK [193]

Answer:

Fruits: 107

Vegetables: 56.5

Step-by-step explanation:

Average is found by adding all of the values together and then dividing by the number of values that there are.

So for fruits, you would do 62+55+49+50+98+328 and then divide that whole thing by six.

Same for veggies, 34+122+57+21+79+26 with the answer divided by six.
