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 !
