To find out how much Len needs to earn in the sixth month to have an average monthly earning of at least $3130, first calculate the total amount he needs to have earned over six months: $3130 * 6 = $18780. Then, sum the amounts he has already earned: $3810 + $2330 + $3380 + $2310 + $3420 = $15250. Subtract this total from the six-month requirement: $18780 - $15250 = $3530. Therefore, Len must earn at least $3530 in the sixth month.
