A store sells a package of 15 trading cards for ​$7.20. Use pencil and paper. Explain how you can tell that the unit price per card is less than​ $1. What is the unit price per​ card?

If you do 15 divided by 7.20 it’s $2.08 each card. Hoped it helped!

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
