A car rents for $260 per week plus $0.10 per mile. Find the rental cost for a three week trip of 800 miles

(260 * 3) + (0.1 * 800) = $________

To find the rental cost for a three-week trip of 800 miles, you need to calculate the cost of renting the car for three weeks, and then add the cost of the miles driven.

Step 1: Calculate the cost for three weeks of rental:
The car rents for $260 per week, so for three weeks, the cost would be 3 * $260 = $780.

Step 2: Calculate the cost for the miles driven:
The car rental charges $0.10 per mile. For 800 miles, the cost would be 800 * $0.10 = $80.

Step 3: Add the cost of rental and the cost of the miles driven:
$780 (three-week rental cost) + $80 (cost for 800 miles) = $860.

Therefore, the rental cost for a three-week trip of 800 miles would be $860.
