In this word problem, the rate of change refers to how much the cost increases with each additional scoop of ice cream. Since each scoop of ice cream costs $1.50, the rate of change is $1.50 per scoop. This means that for each additional scoop, you pay $1.50 more.

Therefore:

1.5
1.5

is the correct rate of change.
