In one week, Jake can eat 3 papayas, his brother can eat 5 papayas, and his father can eat 4 papayas.  To account for 4 weeks, how many papayas does Jake need to buy from the farmer’s market?
In one week, the 3 men can eat 3 + 5 + 4 = <<3+5+4=12>>12 papayas.
For 4 weeks, Jake will need to buy 12 x 4 = <<12*4=48>>48 papayas.
