Solution
Step 1
We calculate the total cost in 2004 by multiplying the weekly rate by the number of weeks in a year.
C_{2004} = 4 \times 52
Step 2
We calculate the total cost in 2005 by summing the cost for the first 40 weeks and the remaining 12 weeks at their respective rates.
C_{2005} = 3 \times 40 + 2 \times 12
Step 3
We find how much less the 2005 cost is compared to the 2004 cost by subtracting the two totals.
C_{2004} - C_{2005} = 208 - 144 = 64
Answer
64USD
