NEED HELP PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!
You are in charge of decorating for the spring dance. You purchase 5 bags of balloons and 2 rolls of crepe paper for $38. You soon realize that this is not enough to decorate the entire gym. On your second trip to the store, you spend $128 on 12 bags of balloons and 14 rolls of crepe paper. Assume the sales tax is included in the price.
a) What was the price of a bag of balloons?
b) How much does each roll of crepe paper cost?
