a. Joan and Dave harvest a total of 1 200 kg of olives from their grove.-(FALSE) 600x20=12000

b. The olives from 2 trees fit into 1 bin.-(FALSE) 20/2=10

c. If they had to store all their harvested olives, Dave and Joan would need 1 200 bins.-12000/10=1200

d. In an 8 hour day, the press can process 2 000 kg of olives.-(TRUE) 250x8=2000

e. It takes 8 days to process Dave and Joan’s olives.-250x80=20000


f. If all 10 growers in Joan and Dave’s group have the same sized groove, each produces 1 440 L of oil.-(TRUE) 1440x10=14400


g. Joan and Dave’s olives produce 5 760 bottles of oil.-(False) 5760x20=115200


h. If Joan and Dave pack all their bottles of oil in cartons, they’ll need 188 of them.-14400/12=12200


i. Each carton holds 5 L of oil.-(TRUE) 5x20=100  L


j. If Dave and Joan sell all their oil, they will earn $115,200.-$20x$57600=$115200
