Monica bought 2 drinks and 3 bags of popcorn for $22. Her dad bought 4 drinks for $20. How much is each drink and bag of popcorn? One equation looks like: 2x + 3y = 22
Find the other equation and solve the system.

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
