To find the profit the manufacturer made from the warranties, we need to follow these steps:

  1. Calculate the total revenue from selling the warranties.
  2. Determine the total amount the manufacturer has to pay out for honoring the warranties.
  3. Subtract the total payout from the total revenue to find the profit.

Step 1: Total Revenue from Warranties

The cost of one warranty is $17. If the manufacturer sells 475,360 warranties, the total revenue from selling the warranties is: \[ \text{Total Revenue} = \text{Number of Warranties} \times \text{Cost per Warranty} \] \[ \text{Total Revenue} = 475,360 \times 17 \] \[ \text{Total Revenue} = 8,078,120 \]

Step 2: Total Payout for Warranties

The manufacturer has to honor 7.5% of the sold warranties. First, we calculate how many warranties will be honored: \[ \text{Warranties Honored} = 0.075 \times 475,360 \] \[ \text{Warranties Honored} = 35,152 \]

Now, we need to calculate the total amount the manufacturer has to pay out for these honored warranties. Assuming the cost of honoring a warranty is the same as the cost of the warranty ($17): \[ \text{Total Payout} = \text{Warranties Honored} \times \text{Cost per Warranty} \] \[ \text{Total Payout} = 35,152 \times 17 \] \[ \text{Total Payout} = 597,584 \]

Step 3: Profit Calculation

Now we can calculate the profit: \[ \text{Profit} = \text{Total Revenue} - \text{Total Payout} \] \[ \text{Profit} = 8,078,120 - 597,584 \] \[ \text{Profit} = 7,480,536 \]

Looking at the answer choices, the closest one is: \[ \text{b. } 7,475,036 \]

However, this number does not exactly match our calculation, but it is the nearest option based on the figures given.

Thus, the profit the manufacturer made from the warranties is: b. $7,475,036
