Devon paid for 4 pounds of bananas with a $10 bill. He got back $4.00. What was the cost of 1 pound of bananas?

One dollar and fifty cents

Hi

He paid for 4 pounds of bananas with a 10$ bill. However, they gave him $4 back, so that's mean the total cost for 4 pounds of bananas was for 6 dollars. Now they ask you to find the cost for 1 pound of banana.

4 pounds ... > $6

1 pound ... x (x represents the cost that we are looking for)

Cross multiply

4x = 6

Divide both sides by 4

4x/4 = 6/4

x = 1.5

The final answer is : The cost for 1 pound of banana was for $1.5 dollars.

Good luck!
