On 4 June to 7 June, an average of 43 persimmons were sold and from 8th June to 12 June, an average of 23 persimmons were sold. $265 worth of persimmons were sold from 13 June to 23 June. Given that a persimmon was sold for $5, find the average number of persimmons sold from 4 June to 23 June.
Number of persimmons sold from 13 June to 23 June
= 265 ÷ 5
= 53

Number of days from 4 June to 7 June
= 7 - 4 + 1
= 4

Number of days from 8 June to 12 of June
= 12 - 8 + 1
= 5

Total number of persimmons sold
= (4 x 43) + (5 x 23) + 53
= 172 + 115 + 53
= 340

Number of days from 4 June to 23 June
= 23 - 4 + 1
= 20

Average number of persimmons sold
= 340 ÷ 20
= 17

Answer(s): 17
