PLEASE HELP!! WILL MEDAL A bicycle store costs $2400 per month to operate. The store pays an average of $60 per bike. The average selling price of each bike is $120. How many bikes must the store sell each month to break even? @campbell_st

I think it would be 40 bikes. To figure this out, I did 120-60 first, which = 60. Then I divided 2400, the store's cost each month, and the answer was 40, which should be the amount of bikes needed to be sold each month to break even.

You split $1500 between two savings accounts. Account A pays annual 5% interest and Account B pays 4% annual interest. After one year, you have earned a total of $69.50 in interest. How much money did you invest in each account?
