Caleb spent 34.95 on 5 pounds of coffee. how much was the coffee per pound?
horsena [70]
It would be $6.99. All you have to do is divide the total (34.95) by pounds of coffee (5). 34.95 / 5 will give you 6.99! You can check this by doing 6.99 * 5, which would again give you 34.95. Contact me if you need any more help. :^)
