Answer:
<u>The total number of pieces of fruit that Charlie can gather ranges from 11 to 19.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Numbers of apples and plums are 10-partners, it means that the sum of apples and plums is 10.
Number of apples and pears are the same.
2. How many pieces of fruit can Charlie gather?
Apples = a
Plums = p
Pears = s
a + p = 10
Possible values of a and p:
1 + 9, 2 + 8, 3 + 7, 4 + 6, 5 + 5, 6 + 4, 7 + 3, 8 + 2, 9 + 1
Possible values of s:
1, 2, 3, 4, 5, 6, 7, 8, or 9
<u>Therefore, the total number of pieces of fruit that Charlie can gather ranges from 11 to 19.</u>
