Mark bought 2 pounds of tomatoes for $5 per pound and 5 pounds of apples, at $6 per pound. How much did he spend in total? Let's be accurate as possible.
Mark bought 2 pounds of tomatoes for $5 / pound * 2 pounds = $10. Mark bought 5 pounds of apples for $6 / pound * 5 pounds = $30. Now add those two quantities to find Mark's total spending: $30 + $10 = $40.
The answer: 40.
