What does p hold in the loop?

Short answer. The index, not the value.

What is the final total?

40.

Remember

p is the index
L[p] is the value

Index or value? Predict this output before the answer. T is the total, p is the index. Multiply each value by its index. Zero, plus ten, plus thirty. Forty. Remember two things. P is the index. L of p is the value.
