Expected Inspection Cost Until the First Defect

A quality line inspects items one at a time; each item is defective independently with probability $0.05$. Inspection stops at the first defective item. Each inspection (defective or not) costs an i.i.d. amount $C_i$ with $E[C_i]=\$8$, independent of the defect outcomes. Let $N$ be the number of items inspected. Find the expected total inspection cost $E\!\left[\sum_{i=1}^N C_i\right]$.
