Cost of Lemons
Number of lemons 1 3 5 9 12
Cost $0.89 $2.67 $4.45 $8.01 $10.68
Determine whether a linear function or an exponential function would best model the increase in the cost of lemons, and why.(1 point)

Reason: Each additional lemon adds $0.89. (Differences: (2.67−0.89)/2 = (4.45−2.67)/2 = (8.01−4.45)/4 = (10.68−8.01)/3 = $0.89 per lemon.)
