1.5 deep.
you subtract 2.25 of air space from the total depth 3.75
3.75-2.25=1.5
52.9109 in pounds if that's what your asking.
The fraction would be 37 out of 42. You basically divide the two and get something around 88%.
The scenario represents a linear function. The rate is at a constant increase therefore it is linear.
Linear because it’s a constant rate
Since it’s doubled, and doesn’t go at a constant rate, it is a exponential function
Exponential since it increases by a multiplicative rate. It’s not constant
