You were told the interest rate used was 10% per year, but no first cost or projected salvage value were provided and you want to know them.

Table Summary: A table divided into 4 columns shows the AW analysis for an equipment for 5 years. The column headers are marked as: Years retained; AW of first cost in dollars; AW of operating cost in dollars per year; and AW of salvage value in dollars.
